+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

+ * From Phillips' datasheet:
+ *
+ * The PCF8563 is a CMOS real-time clock/calendar optimized for low power
+ * consumption. A programmable clock output, interupt output and voltage
+ * low detector are also provided. All address and data are transferred
+ * serially via two-line bidirectional I2C-bus. Maximum bus speed is
+ * 400 kbits/s. The built-in word address register is incremented
+ * automatically after each written or read byte.

+ * $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.

+ *  Revision 1.20  2005/03/04 08:16:18  starvik
+ *  Merge of Linux 2.6.11.
+ *
+ *  Revision 1.19  2005/01/14 10:07:59  starvik
+ *  Fixed warning.
+ *
+ *  Revision 1.18  2005/01/12 08:10:14  starvik
+ *  Readded the change of frametype when handling kernel page fault fixup
+ *  for v10. This is necessary to avoid that the CPU remakes the faulting
+ *  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.
+ *
+ *  Revision 1.12  2004/09/29 06:16:04  starvik
+ *  Use instruction_pointer
+ *
  *  Revision 1.11  2004/05/14 07:58:05  starvik
  *  Merge of changes from 2.4

-          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.
-
-          Say Y here and to the driver for your graphics board below if you
-          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.

+ * WARNING - magic here

+ * Ok, this is a horrid hack below, but marginally better than the
+ * alternatives.  What we really want is just to initialize
+ * hvReleaseData in C as in the #if 0 section here.  However, gcc
+ * refuses to believe that (u32)&x is a constant expression, so will
+ * not allow the xMsNucDataOffset field to be properly initialized.
+ * So, we declare hvReleaseData in inline asm instead.  We use inline
+ * asm, rather than a .S file, because the assembler won't generate
+ * the necessary relocation for the LparMap either, unless that symbol
+ * is declared in the same source file.  Finally, we put the asm in a
+ * dummy, attribute-used function, instead of at file scope, because
+ * file scope asms don't allow contraints.  We want to use the "i"
+ * constraints to put sizeof() and offsetof() expressions in there,
+ * because including asm/offsets.h in C code then stringifying causes
+ * all manner of warnings.
