-          This driver does not support the TI 4000M TravelMate and the ACER
-          486/DX4/75 because they don't have compliant BIOSes. Many "green"
-          desktop machines also don't have compliant BIOSes, and this driver
-          may cause those machines to panic during the boot phase.

           Generally, if you don't have a battery in your machine, there isn't
           much point in using this driver and you should say N. If you get
           random kernel OOPSes or reboots that don't seem to be related to
           anything, try disabling/enabling this option (or disabling/enabling
           APM in your BIOS).

-          enabled.
-          2) pass the "no-hlt" option to the kernel
-          3) switch on floating point emulation in the kernel and pass
-          the "no387" option to the kernel
-          4) pass the "floppy=nodma" option to the kernel
-          5) pass the "mem=4M" option to the kernel (thereby disabling
-          all but the first 4 MB of RAM)
-          6) make sure that the CPU is not over clocked.
-          7) read the sig11 FAQ at <http://www.bitwizard.nl/sig11/>
-          8) disable the cache from your BIOS settings
-          9) install a fan for the video card or exchange video RAM
-          10) install a better fan for the CPU
-          11) exchange RAM chips
-          12) exchange the motherboard.

-          This provides a character device for each MTD device present in
-          the system, allowing the user to read and write directly to the
-          memory chips, and also use ioctl() to obtain information about
-          the device, or to erase parts of it.

-config MTD_BLOCK

-        depends on ETRAX_AXISFLASHMAP
-        default y
-        ---help---
-          Although most flash chips have an erase size too large to be useful
-          as block devices, it is possible to use MTD devices which are based
-          on RAM chips in this manner. This block device is a user of MTD
-          devices performing that function.
-
-          At the moment, it is also required for the Journalling Flash File
-          System(s) to obtain a handle on the MTD device when it's mounted
-          (although JFFS and JFFS2 don't actually use any of the functionality
-          of the mtdblock device).
-
-          Later, it may be extended to perform read/erase/modify/write cycles
-          on flash chips to emulate a smaller block size. Needless to say,
-          this is very unsafe, but could be useful for file systems which are
-          almost never written to.
-
-          You do not need this option for use with the DiskOnChip devices. For
-          those, enable NFTL support (CONFIG_NFTL) instead.

-config MTD_PARTITIONS

-        depends on ETRAX_AXISFLASHMAP

-        help
-          If you have a device which needs to divide its flash chip(s) up
-          into multiple 'partitions', each of which appears to the user as
-          a separate MTD device, you require this option to be enabled. If
-          unsure, say 'Y'.
-
-          Note, however, that you don't need this option for the DiskOnChip
-          devices. Partitioning on NFTL 'devices' is a different - that's the
-          'normal' form of partitioning used on a block device.

+Creation of the self-extracting compressed kernel image (vmlinuz)
+-----------------------------------------------------------------
+$Id: README,v 1.1 2003/08/21 09:37:03 johana Exp $
+
+This can be slightly confusing because it's a process with many steps.
+
+The kernel object built by the arch/etrax100/Makefile, vmlinux, is split
+by that makefile into text and data binary files, vmlinux.text and
+vmlinux.data.
+
+Those files together with a ROM filesystem can be catted together and
+burned into a flash or executed directly at the DRAM origin.
+
+They can also be catted together and compressed with gzip, which is what
+happens in this makefile. Together they make up piggy.img.
+
+The decompressor is built into the file decompress.o. It is turned into
+the binary file decompress.bin, which is catted together with piggy.img
+into the file vmlinuz. It can be executed in an arbitrary place in flash.
+
+Be careful - it assumes some things about free locations in DRAM. It
+assumes the DRAM starts at 0x40000000 and that it is at least 8 MB,
+so it puts its code at 0x40700000, and initial stack at 0x40800000.

+/*!***************************************************************************
+*!
+*! FILE NAME  : i2c.c
+*!
+*! DESCRIPTION: implements an interface for IIC/I2C, both directly from other
+*!              kernel modules (i2c_writereg/readreg) and from userspace using
+*!              ioctl()'s
+*!
+*! Nov 30 1998  Torbjorn Eliasson  Initial version.
+*!              Bjorn Wesen        Elinux kernel version.
+*! Jan 14 2000  Johan Adolfsson    Fixed PB shadow register stuff -
+*!                                 don't use PB_I2C if DS1302 uses same bits,
+*!                                 use PB.
+*| June 23 2003 Pieter Grimmerink  Added 'i2c_sendnack'. i2c_readreg now
+*|                                 generates nack on last received byte,
+*|                                 instead of ack.
+*|                                 i2c_getack changed data level while clock
+*|                                 was high, causing DS75 to see  a stop condition

+ * This may be useful in other OS than Linux so use 2 space indentation...
+ *
+ * $Log: fasttimer.c,v $
+ * Revision 1.11  2005/01/04 11:15:46  starvik
+ * Don't share timer IRQ.
+ *
+ * Revision 1.10  2004/12/07 09:19:38  starvik
+ * Corrected includes.
+ * Use correct interrupt macros.
+ *
+ * Revision 1.9  2004/05/14 10:18:58  starvik
+ * Export fast_timer_list
+ *
+ * Revision 1.8  2004/05/14 07:58:03  starvik
+ * Merge of changes from 2.4
+ *
+ * Revision 1.7  2003/07/10 12:06:14  starvik
+ * Return IRQ_NONE if irq wasn't handled
+ *
+ * Revision 1.6  2003/07/04 08:27:49  starvik
+ * Merge of Linux 2.5.74
+ *
+ * Revision 1.5  2003/06/05 10:16:22  johana
+ * New INTR_VECT macros.
+ *
+ * Revision 1.4  2003/06/03 08:49:45  johana
+ * Fixed typo.
+ *
+ * Revision 1.3  2003/06/02 12:51:27  johana
+ * Now compiles.
+ * Commented some include files that probably can be removed.
+ *
+ * Revision 1.2  2003/06/02 12:09:41  johana
+ * Ported to ETRAX FS using the trig interrupt instead of timer1.
+ *
+ * Revision 1.3  2002/12/12 08:26:32  starvik
+ * Don't use C-comments inside CVS comments
+ *
+ * Revision 1.2  2002/12/11 15:42:02  starvik
+ * Extracted v10 (ETRAX 100LX) specific stuff from arch/cris/kernel/
+ *
+ * Revision 1.1  2002/11/18 07:58:06  starvik
+ * Fast timers (from Linux 2.4)
+ *
+ * Revision 1.5  2002/10/15 06:21:39  starvik
+ * Added call to init_waitqueue_head
+ *
+ * Revision 1.4  2002/05/28 17:47:59  johana
+ * Added del_fast_timer()
+ *
+ * Revision 1.3  2002/05/28 16:16:07  johana
+ * Handle empty fast_timer_list
+ *
+ * Revision 1.2  2002/05/27 15:38:42  johana
+ * Made it compile without warnings on Linux 2.4.
+ * (includes, wait_queue, PROC_FS and snprintf)
+ *
+ * Revision 1.1  2002/05/27 15:32:25  johana
+ * arch/etrax100/kernel/fasttimer.c v1.8 from the elinux tree.
+ *
+ * Revision 1.8  2001/11/27 13:50:40  pkj
+ * Disable interrupts while stopping the timer and while modifying the
+ * list of active timers in timer1_handler() as it may be interrupted
+ * by other interrupts (e.g., the serial interrupt) which may add fast
+ * timers.
+ *
+ * Revision 1.7  2001/11/22 11:50:32  pkj
+ * * Only store information about the last 16 timers.
+ * * proc_fasttimer_read() now uses an allocated buffer, since it
+ *   requires more space than just a page even for only writing the
+ *   last 16 timers. The buffer is only allocated on request, so
+ *   unless /proc/fasttimer is read, it is never allocated.
+ * * Renamed fast_timer_started to fast_timers_started to match
+ *   fast_timers_added and fast_timers_expired.
+ * * Some clean-up.
+ *
+ * Revision 1.6  2000/12/13 14:02:08  johana
+ * Removed volatile for fast_timer_list
+ *
+ * Revision 1.5  2000/12/13 13:55:35  johana
+ * Added DEBUG_LOG, added som cli() and cleanup
+ *
+ * Revision 1.4  2000/12/05 13:48:50  johana
+ * Added range check when writing proc file, modified timer int handling
+ *
+ * Revision 1.3  2000/11/23 10:10:20  johana
+ * More debug/logging possibilities.
+ * Moved GET_JIFFIES_USEC() to timex.h and time.c
+ *
+ * Revision 1.2  2000/11/01 13:41:04  johana
+ * Clean up and bugfixes.
+ * Created new do_gettimeofday_fast() that gets a timeval struct
+ * with time based on jiffies and *R_TIMER0_DATA, uses a table
+ * for fast conversion of timer value to microseconds.
+ * (Much faster the standard do_gettimeofday() and we don't really
+ * wan't to use the true time - we wan't the "uptime" so timers don't screw up
+ * when we change the time.
+ * TODO: Add efficient support for continuous timers as well.
+ *
+ * Revision 1.1  2000/10/26 15:49:16  johana
+ * Added fasttimer, highresolution timers.

+ *  kgdb usage notes:
+ *  -----------------
+ *
+ * If you select CONFIG_ETRAX_KGDB in the configuration, the kernel will be
+ * built with different gcc flags: "-g" is added to get debug infos, and
+ * "-fomit-frame-pointer" is omitted to make debugging easier. Since the
+ * resulting kernel will be quite big (approx. > 7 MB), it will be stripped
+ * before compresion. Such a kernel will behave just as usually, except if
+ * given a "debug=<device>" command line option. (Only serial devices are
+ * allowed for <device>, i.e. no printers or the like; possible values are
+ * machine depedend and are the same as for the usual debug device, the one
+ * for logging kernel messages.) If that option is given and the device can be
+ * initialized, the kernel will connect to the remote gdb in trap_init(). The
+ * serial parameters are fixed to 8N1 and 115200 bps, for easyness of
+ * implementation.
+ *
+ * To start a debugging session, start that gdb with the debugging kernel
+ * image (the one with the symbols, vmlinux.debug) named on the command line.
+ * This file will be used by gdb to get symbol and debugging infos about the
+ * kernel. Next, select remote debug mode by
+ *    target remote <device>
+ * where <device> is the name of the serial device over which the debugged
+ * machine is connected. Maybe you have to adjust the baud rate by
+ *    set remotebaud <rate>
+ * or also other parameters with stty:
+ *    shell stty ... </dev/...
+ * If the kernel to debug has already booted, it waited for gdb and now
+ * connects, and you'll see a breakpoint being reported. If the kernel isn't
+ * running yet, start it now. The order of gdb and the kernel doesn't matter.
+ * Another thing worth knowing about in the getting-started phase is how to
+ * debug the remote protocol itself. This is activated with
+ *    set remotedebug 1
+ * gdb will then print out each packet sent or received. You'll also get some
+ * messages about the gdb stub on the console of the debugged machine.
+ *
+ * If all that works, you can use lots of the usual debugging techniques on
+ * the kernel, e.g. inspecting and changing variables/memory, setting
+ * breakpoints, single stepping and so on. It's also possible to interrupt the
+ * debugged kernel by pressing C-c in gdb. Have fun! :-)
+ *
+ * The gdb stub is entered (and thus the remote gdb gets control) in the
+ * following situations:
+ *
+ *  - If breakpoint() is called. This is just after kgdb initialization, or if
+ *    a breakpoint() call has been put somewhere into the kernel source.
+ *    (Breakpoints can of course also be set the usual way in gdb.)
+ *    In eLinux, we call breakpoint() in init/main.c after IRQ initialization.
+ *
+ *  - If there is a kernel exception, i.e. bad_super_trap() or die_if_kernel()
+ *    are entered. All the CPU exceptions are mapped to (more or less..., see
+ *    the hard_trap_info array below) appropriate signal, which are reported
+ *    to gdb. die_if_kernel() is usually called after some kind of access
+ *    error and thus is reported as SIGSEGV.
+ *
+ *  - When panic() is called. This is reported as SIGABRT.
+ *
+ *  - If C-c is received over the serial line, which is treated as
+ *    SIGINT.
+ *
+ * Of course, all these signals are just faked for gdb, since there is no
+ * signal concept as such for the kernel. It also isn't possible --obviously--
+ * to set signal handlers from inside gdb, or restart the kernel with a
+ * signal.
+ *
+ * Current limitations:
+ *
+ *  - While the kernel is stopped, interrupts are disabled for safety reasons
+ *    (i.e., variables not changing magically or the like). But this also
+ *    means that the clock isn't running anymore, and that interrupts from the
+ *    hardware may get lost/not be served in time. This can cause some device
+ *    errors...
+ *
+ *  - When single-stepping, only one instruction of the current thread is
+ *    executed, but interrupts are allowed for that time and will be serviced
+ *    if pending. Be prepared for that.
+ *
+ *  - All debugging happens in kernel virtual address space. There's no way to
+ *    access physical memory not mapped in kernel space, or to access user
+ *    space. A way to work around this is using get_user_long & Co. in gdb
+ *    expressions, but only for the current process.
+ *
+ *  - Interrupting the kernel only works if interrupts are currently allowed,
+ *    and the interrupt of the serial line isn't blocked by some other means
+ *    (IPL too high, disabled, ...)
+ *
+ *  - The gdb stub is currently not reentrant, i.e. errors that happen therein
+ *    (e.g. accessing invalid memory) may not be caught correctly. This could
+ *    be removed in future by introducing a stack of struct registers.
+ *
+ */
+
+/*
+ *  To enable debugger support, two things need to happen.  One, a
+ *  call to kgdb_init() is necessary in order to allow any breakpoints
+ *  or error conditions to be properly intercepted and reported to gdb.
+ *  Two, a breakpoint needs to be generated to begin communication.  This
+ *  is most easily accomplished by a call to breakpoint().
+ *
+ *    The following gdb commands are supported:
+ *
+ * command          function                               Return value
+ *
+ *    g             return the value of the CPU registers  hex data or ENN
+ *    G             set the value of the CPU registers     OK or ENN
+ *
+ *    mAA..AA,LLLL  Read LLLL bytes at address AA..AA      hex data or ENN
+ *    MAA..AA,LLLL: Write LLLL bytes at address AA.AA      OK or ENN
+ *
+ *    c             Resume at current address              SNN   ( signal NN)
+ *    cAA..AA       Continue at address AA..AA             SNN
+ *
+ *    s             Step one instruction                   SNN
+ *    sAA..AA       Step one instruction from AA..AA       SNN
+ *
+ *    k             kill
+ *
+ *    ?             What was the last sigval ?             SNN   (signal NN)
+ *
+ *    bBB..BB       Set baud rate to BB..BB                OK or BNN, then sets
+ *                                                         baud rate
+ *
+ * All commands and responses are sent with a packet which includes a
+ * checksum.  A packet consists of
+ *
+ * $<packet info>#<checksum>.
+ *
+ * where
+ * <packet info> :: <characters representing the command or response>
+ * <checksum>    :: < two hex digits computed as modulo 256 sum of <packetinfo>>
+ *
+ * When a packet is received, it is first acknowledged with either '+' or '-'.
+ * '+' indicates a successful transfer.  '-' indicates a failed transfer.
+ *
+ * Example:
+ *
+ * Host:                  Reply:
+ * $m0,10#2a               +$00010203040506070809101112131415#42

+##      The bootrom copies data from the NAND flash to the internal RAM but
+##      due to a bug/feature we can only trust the 256 first bytes. So this
+##      code copies more data from NAND flash to internal RAM. Obvioulsy this
+##      code must fit in the first 256 bytes so alter with care.
+##
+##      Some notes about the bug/feature for future reference:
+##        The bootrom copies the first 127 KB from NAND flash to internal
+##        memory. The problem is that it does a bytewise copy. NAND flashes
+##        does autoincrement on the address so for a 16-bite device each
+##        read/write increases the address by two. So the copy loop in the
+##        bootrom will discard every second byte. This is solved by inserting
+##        zeroes in every second byte in the first erase block.
+##
+##        The bootrom also incorrectly assumes that it can read the flash
+##        linear with only one read command but the flash will actually
+##        switch between normal area and spare area if you do that so we
+##        can't trust more than the first 256 bytes.

+ *  Fixed warning.

+ *  Revision 1.18  2005/01/12 08:10:14  starvik
+ *  Readded the change of frametype when handling kernel page fault fixup

+ *  access.
+ *
+ *  Revision 1.17  2005/01/11 13:53:05  starvik
+ *  Use raw_printk.
+ *
+ *  Revision 1.16  2004/12/17 11:39:41  starvik
+ *  SMP support.
+ *
+ *  Revision 1.15  2004/11/23 18:36:18  starvik
+ *  Stack is now non-executable.
+ *  Signal handler trampolines are placed in a reserved page mapped into all
+ *  processes.
+ *
+ *  Revision 1.14  2004/11/23 07:10:21  starvik
+ *  Moved find_fixup_code to generic code.
+ *
+ *  Revision 1.13  2004/11/23 07:00:54  starvik
+ *  Actually use the execute permission bit in the MMU. This makes it possible
+ *  to prevent e.g. attacks where executable code is put on the stack.

- * Semaphores are implemented using a two-way counter:

- * variable is a count of such acquires.
- *
- * Notably, the inline "up()" and "down()" functions can
- * efficiently test if they need to do any extra work (up
- * needs to do something only if count was negative before
- * the increment operation.
- *
- * "sleeping" and the contention routine ordering is protected
- * by the spinlock in the semaphore's waitqueue head.
- *
- * Note that these functions are only called when there is
- * contention on the lock, and as such all this is the
- * "non-critical" part of the whole semaphore business. The
- * critical part is the inline stuff in <asm/semaphore.h>
- * where we want to avoid any extra jumps and calls.

- *    (a) synchronize with the "sleeper" count and (b) make sure

-          The frame buffer device provides an abstraction for the graphics
-          hardware. It represents the frame buffer of some video hardware and
-          allows application software to access the graphics hardware through
-          a well-defined interface, so the software doesn't need to know
-          anything about the low-level (hardware register) stuff.
-
-          Frame buffer devices work identically across the different
-          architectures supported by Linux and make the implementation of
-          application programs easier and more portable; at this point, an X
-          server exists which uses the frame buffer device exclusively.
-          On several non-X86 architectures, the frame buffer device is the
-          only way to use the graphics hardware.
-
-          The device is accessed through special device nodes, usually located
-          in the /dev directory, i.e. /dev/fb*.
-
-          You need an utility program called fbset to make full use of frame
-          buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
-          and the Framebuffer-HOWTO at <http://www.tldp.org/docs.html#howto>
-          for more information.

-          are compiling a kernel for a non-x86 architecture.
-
-          If you are compiling for the x86 architecture, you can say Y if you
-          want to play with it, but it is not essential. Please note that
-          running graphical applications that directly touch the hardware
-          (e.g. an accelerated X server) and that are not frame buffer
-          device-aware may cause unexpected results. If unsure, say N.

-         * We also have some monkey business with the PCI devices within the
-         * VT82C686B south bridge itself. This chip actually has 7 functions on
-         * its IDSEL. Function 0 is the actual south bridge, function 1 is IDE,
-         * and function 4 is some special stuff. The other 4 functions are just
-         * regular PCI devices bundled in the chip. 2 and 3 are USB UHCIs and 5
-         * and 6 are audio (not supported on the Adirondack).
-         *
-         * This is where the monkey business begins. PCI devices are supposed
-         * to signal normal PCI interrupts. But the 4 functions in question are
-         * located in the south bridge chip, which is designed with the
-         * assumption that it will be fielding PCI INTA-D interrupts rather
-         * than generating them. Here's what it does. Each of the functions in
-         * question routes its interrupt to one of the IRQs on the 8259 thingy.
-         * Which one? It looks at the Interrupt Line register in the PCI config
-         * space, even though the PCI spec says it's for BIOS/OS interaction
-         * only.
-         *
-         * How do we deal with this? We take these interrupts via 8259 IRQs as
-         * we have to. We return the desired IRQ numbers from this routine when
-         * called for the functions in question. The PCI scan code will then
-         * stick our return value into the Interrupt Line register in the PCI
-         * config space, and the interrupt will actually go there. We identify
-         * these functions within the south bridge IDSEL by their interrupt pin
-         * numbers, as the VT82C686B has 04 in the Interrupt Pin register for
-         * USB and 03 for audio.

-        ---help---
-          If you say Y here, you will get support for terminal devices with
-          display and keyboard devices. These are called "virtual" because you
-          can run several virtual terminals (also called virtual consoles) on
-          one physical terminal. This is rather useful, for example one
-          virtual terminal can collect system messages and warnings, another
-          one can be used for a text-mode user session, and a third could run
-          an X session, all in parallel. Switching between virtual terminals
-          is done with certain key combinations, usually Alt-<function key>.
-
-          The setterm command ("man setterm") can be used to change the
-          properties (such as colors or beeping) of a virtual terminal. The
-          man page console_codes(4) ("man console_codes") contains the special
-          character sequences that can be used to change those properties
-          directly. The fonts used on virtual terminals can be changed with
-          the setfont ("man setfont") command and the key bindings are defined
-          with the loadkeys ("man loadkeys") command.
-
-          You need at least one virtual terminal device in order to make use
-          of your keyboard and monitor. Therefore, only people configuring an
-          embedded system would want to say N here in order to save some
-          memory; the only way to log into such a system is then via a serial
-          or network connection.

-          The system console is the device which receives all kernel messages
-          and warnings and which allows logins in single user mode. If you
-          answer Y here, a virtual terminal (the device used to interact with
-          a physical terminal) can be used as system console. This is the most
-          common mode of operations, so you should say Y here unless you want
-          the kernel messages be output only to a serial port (in which case
-          you should say Y to "Console on serial port", below).
-
-          If you do say Y here, by default the currently visible virtual
-          terminal (/dev/tty0) will be used as system console. You can change
-          that with a kernel command line option such as "console=tty3" which
-          would use the third virtual terminal as system console. (Try "man

-        ---help---
-          A pseudo terminal (PTY) is a software device consisting of two
-          halves: a master and a slave. The slave device behaves identical to
-          a physical terminal; the master device is used by a process to
-          read data from and write data to the slave, thereby emulating a
-          terminal. Typical programs for the master side are telnet servers
-          and xterms.
-
-          Linux has traditionally used the BSD-like names /dev/ptyxx for
-          masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
-          has a number of problems. The GNU C library glibc 2.1 and later,
-          however, supports the Unix98 naming standard: in order to acquire a
-          pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
-          terminal is then made available to the process and the pseudo
-          terminal slave can be accessed as /dev/pts/<number>. What was
-          traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
-
-          The entries in /dev/pts/ are created on the fly by a virtual
-          file system; therefore, if you say Y here you should say Y to
-          "/dev/pts file system for Unix98 PTYs" as well.
-
-          If you want to say Y here, you need to have the C library glibc 2.1
-          or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
-          Read the instructions in <file:Documentation/Changes> pertaining to
-          pseudo terminals. It's safe to say N.

-        help
-          The maximum number of Unix98 PTYs that can be used at any one time.

-          machines which support incoming telnet/rlogin/ssh connections and/or
-          serve several X terminals may want to increase this: every incoming
-          connection and every xterm uses up one PTY.
-
-          When not in use, each additional set of 256 PTYs occupy
-          approximately 8 KB of kernel memory on 32-bit architectures.

+        /* These are here in an effort to more fully work around
+         * Spitfire Errata #51.  Essentially, if a memory barrier
+         * occurs soon after a mispredicted branch, the chip can stop
+         * executing instructions until a trap occurs.  Therefore, if
+         * interrupts are disabled, the chip can hang forever.
+         *
+         * It used to be believed that the memory barrier had to be
+         * right in the delay slot, but a case has been traced
+         * recently wherein the memory barrier was one instruction
+         * after the branch delay slot and the chip still hung.  The
+         * offending sequence was the following in sym_wakeup_done()
+         * of the sym53c8xx_2 driver:
+         *
+         *      call    sym_ccb_from_dsa, 0
+         *       movge  %icc, 0, %l0
+         *      brz,pn  %o0, .LL1303
+         *       mov    %o0, %l2
+         *      membar  #LoadLoad
+         *
+         * The branch has to be mispredicted for the bug to occur.
+         * Therefore, we put the memory barrier explicitly into a
+         * "branch always, predicted taken" delay slot to avoid the
+         * problem case.

 This port to the NEC V850E processor supports the following platforms:
 
-   + The gdb v850e simulator (CONFIG_V850E_SIM).
-
-   + The Midas labs RTE-V850E/MA1-CB and RTE-V850E/NB85E-CB evaluation boards
-     (CONFIG_RTE_CB_MA1 and CONFIG_RTE_CB_NB85E).  This support has only been
-     tested when running with the Multi-debugger monitor ROM (for the Green
-     Hills Multi debugger).  The optional NEC Solution Gear RTE-MOTHER-A
-     motherboard is also supported, which allows PCI boards to be used
-     (CONFIG_RTE_MB_A_PCI).
-
-   + The Midas labs RTE-V850E/ME2-CB evaluation board (CONFIG_RTE_CB_ME2).
-     This has only been tested using a kernel downloaded via an ICE connection
-     using the Multi debugger.  Support for the RTE-MOTHER-A is present, but
-     hasn't been tested (unlike the other Midas labs cpu boards, the
-     RTE-V850E/ME2-CB includes an ethernet adaptor).
-
-   + The NEC AS85EP1 V850E evaluation chip/board (CONFIG_V850E_AS85EP1).
-
-   + The NEC `Anna' (board/chip) implementation of the V850E2 processor
-     (CONFIG_V850E2_ANNA).
-
-   + The sim85e2c and sim85e2s simulators, which are verilog simulations of
-     the V850E2 NA85E2C/NA85E2S cpu cores (CONFIG_V850E2_SIM85E2C and

+To get a default kernel configuration for a particular platform, you can
+use a <platform>_defconfig make target (e.g., "make rte-me2-cb_defconfig");
+to see which default configurations are possible, look in the directory
+"arch/v850/configs".
 
 Porting to anything with a V850E/MA1 or MA2 processor should be simple.

- * Semaphores are implemented using a two-way counter:
- * The "count" variable is decremented for each process
- * that tries to acquire the semaphore, while the "sleeping"
- * variable is a count of such acquires.
- *
- * Notably, the inline "up()" and "down()" functions can
- * efficiently test if they need to do any extra work (up
- * needs to do something only if count was negative before
- * the increment operation.
- *
- * "sleeping" and the contention routine ordering is protected
- * by the spinlock in the semaphore's waitqueue head.
- *
- * Note that these functions are only called when there is
- * contention on the lock, and as such all this is the
- * "non-critical" part of the whole semaphore business. The
- * critical part is the inline stuff in <asm/semaphore.h>
- * where we want to avoid any extra jumps and calls.

-/*
- * Logic:
- *  - only on a boundary condition do we need to care. When we go
- *    from a negative count to a non-negative, we wake people up.
- *  - when we go from a non-negative count to a negative do we
- *    (a) synchronize with the "sleeper" count and (b) make sure
- *    that we're on the wakeup list before we synchronize so that
