+/*
+ * PowerPC atomic bit operations.
+ *
+ * Merged version by David Gibson <david@gibson.dropbear.id.au>.
+ * Based on ppc64 versions by: Dave Engebretsen, Todd Inglett, Don
+ * Reed, Pat McCarthy, Peter Bergner, Anton Blanchard.  They
+ * originally took it from the ppc32 code.
+ *
+ * Within a word, bits are numbered LSB first.  Lot's of places make
+ * this assumption by directly testing bits with (val & (1<<nr)).
+ * This can cause confusion for large (> 1 word) bitmaps on a
+ * big-endian system because, unlike little endian, the number of each
+ * bit depends on the word size.
+ *
+ * The bitop functions are defined to work on unsigned longs, so for a
+ * ppc64 system the bits end up numbered:
+ *   |63..............0|127............64|191...........128|255...........196|
+ * and on ppc32:
+ *   |31.....0|63....31|95....64|127...96|159..128|191..160|223..192|255..224|
+ *
+ * There are a few little-endian macros used mostly for filesystem
+ * bitmaps, these work on similar bit arrays layouts, but
+ * byte-oriented:
+ *   |7...0|15...8|23...16|31...24|39...32|47...40|55...48|63...56|
+ *
+ * The main difference is that bit 3-5 (64b) or 3-4 (32b) in the bit
+ * number field needs to be reversed compared to the big-endian bit
+ * fields. This can be achieved by XOR with 0x38 (64b) or 0x18 (32b).
+ *

+ *  controller 1: channels 0-3, byte operations, ports 00-1F
+ *  controller 2: channels 4-7, word operations, ports C0-DF
+ *
+ *  - ALL registers are 8 bits only, regardless of transfer size
+ *  - channel 4 is not used - cascades 1 into 2.
+ *  - channels 0-3 are byte - addresses/counts are for physical bytes
+ *  - channels 5-7 are word - addresses/counts are for physical words
+ *  - transfers must not cross physical 64K (0-3) or 128K (5-7) boundaries
+ *  - transfer count loaded to registers is 1 less than actual count
+ *  - controller 2 offsets are all even (2x offsets for controller 1)
+ *  - page registers for 5-7 don't use data bit 0, represent 128K pages
+ *  - page registers for 0-3 use bit 0, represent 64K pages
+ *
+ * On PReP, DMA transfers are limited to the lower 16MB of _physical_ memory.
+ * On CHRP, the W83C553F (and VLSI Tollgate?) support full 32 bit addressing.
+ * Note that addresses loaded into registers must be _physical_ addresses,
+ * not logical addresses (which may differ if paging is active).
+ *
+ *  Address mapping for channels 0-3:
+ *
+ *   A23 ... A16 A15 ... A8  A7 ... A0    (Physical addresses)
+ *    |  ...  |   |  ... |   |  ... |
+ *    |  ...  |   |  ... |   |  ... |
+ *    |  ...  |   |  ... |   |  ... |
+ *   P7  ...  P0  A7 ... A0  A7 ... A0
+ * |    Page    | Addr MSB | Addr LSB |   (DMA registers)
+ *
+ *  Address mapping for channels 5-7:
+ *
+ *   A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0    (Physical addresses)
+ *    |  ...  |   \   \   ... \  \  \  ... \  \
+ *    |  ...  |    \   \   ... \  \  \  ... \  (not used)
+ *    |  ...  |     \   \   ... \  \  \  ... \
+ *   P7  ...  P1 (0) A7 A6  ... A0 A7 A6 ... A0
+ * |      Page      |  Addr MSB   |  Addr LSB  |   (DMA registers)
+ *
+ * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
+ * and counts _must_ be word-aligned (the lowest address bit is _ignored_ at
+ * the hardware level, so odd-byte transfers aren't possible).
+ *
+ * Transfer count (_not # bytes_) is limited to 64K, represented as actual
+ * count - 1 : 64K => 0xFFFF, 1 => 0x0000.  Thus, count is always 1 or more,
+ * and up to 128K bytes may be transferred on channels 5-7 in one operation.

+ * When CONFIG_PPC_INDIRECT_IO is set, the platform can provide hooks
+ * on all IOs. (Note that this is all 64 bits only for now)
+ *
+ * To help platforms who may need to differenciate MMIO addresses in
+ * their hooks, a bitfield is reserved for use by the platform near the
+ * top of MMIO addresses (not PIO, those have to cope the hard way).
+ *
+ * This bit field is 12 bits and is at the top of the IO virtual
+ * addresses PCI_IO_INDIRECT_TOKEN_MASK.
+ *
+ * The kernel virtual space is thus:
+ *
+ *  0xD000000000000000          : vmalloc

+ *  0xD0000fffffffffff          : end of ioremap region
+ *
+ * Since the top 4 bits are reserved as the region ID, we use thus
+ * the next 12 bits and keep 4 bits available for the future if the
+ * virtual address space is ever to be extended.
+ *
+ * The direct IO mapping operations will then mask off those bits
+ * before doing the actual access, though that only happen when
+ * CONFIG_PPC_INDIRECT_IO is set, thus be careful when you use that

+ *
+ * * __ioremap_at (and the pending __iounmap_at) are low level functions to
+ *   create hand-made mappings for use only by the PCI code and cannot
+ *   currently be hooked. Must be page aligned.

+ * VSID allocation

+ * We first generate a 36-bit "proto-VSID".  For kernel addresses this
+ * is equal to the ESID, for user addresses it is:
+ *      (context << 15) | (esid & 0x7fff)
+ *
+ * The two forms are distinguishable because the top bit is 0 for user
+ * addresses, whereas the top two bits are 1 for kernel addresses.
+ * Proto-VSIDs with the top two bits equal to 0b10 are reserved for
+ * now.
+ *
+ * The proto-VSIDs are then scrambled into real VSIDs with the
+ * multiplicative hash:
+ *
+ *      VSID = (proto-VSID * VSID_MULTIPLIER) % VSID_MODULUS
+ *      where   VSID_MULTIPLIER = 268435399 = 0xFFFFFC7
+ *              VSID_MODULUS = 2^36-1 = 0xFFFFFFFFF
+ *
+ * This scramble is only well defined for proto-VSIDs below
+ * 0xFFFFFFFFF, so both proto-VSID and actual VSID 0xFFFFFFFFF are
+ * reserved.  VSID_MULTIPLIER is prime, so in particular it is
+ * co-prime to VSID_MODULUS, making this a 1:1 scrambling function.
+ * Because the modulus is 2^n-1 we can compute it efficiently without
+ * a divide or extra multiply (see below).
+ *
+ * This scheme has several advantages over older methods:
+ *
+ *      - We have VSIDs allocated for every kernel address
+ * (i.e. everything above 0xC000000000000000), except the very top
+ * segment, which simplifies several things.
+ *
+ *      - We allow for 15 significant bits of ESID and 20 bits of
+ * context for user addresses.  i.e. 8T (43 bits) of address space for
+ * up to 1M contexts (although the page table structure and context
+ * allocation will need changes to take advantage of this).
+ *
+ *      - The scramble function gives robust scattering in the hash
+ * table (at least based on some initial results).  The previous
+ * method was more susceptible to pathological cases giving excessive
+ * hash collisions.

+ * To maintain compatibility with current implementations the sigcontext is

+ * followed by an unstructured (vmx_reserve) field of 69 doublewords.  This
+ * allows the array of vector registers to be quadword aligned independent of
+ * the alignment of the containing sigcontext or ucontext. It is the
+ * responsibility of the code setting the sigcontext to set this pointer to
+ * either NULL (if this processor does not support the VMX feature) or the
+ * address of the first quadword within the allocated (vmx_reserve) area.
+ *
+ * The pointer (v_regs) of vector type (elf_vrreg_t) is type compatible with
+ * an array of 34 quadword entries (elf_vrregset_t).  The entries with
+ * indexes 0-31 contain the corresponding vector registers.  The entry with
+ * index 32 contains the vscr as the last word (offset 12) within the
+ * quadword.  This allows the vscr to be stored as either a quadword (since
+ * it must be copied via a vector register to/from storage) or as a word.
+ * The entry with index 33 contains the vrsave as the first word (offset 0)
+ * within the quadword.
+ *
+ * Part of the VSX data is stored here also by extending vmx_restore
+ * by an additional 32 double words.  Architecturally the layout of

+  * i2c commands

+  * To issue an i2c command, first is to send a parameter block to the

+  * eventually followed by data for a write:
+  *
+  * 0: bus number (from device-tree usually, SMU has lots of busses !)
+  * 1: transfer type/format (see below)
+  * 2: device address. For combined and combined4 type transfers, this
+  *    is the "write" version of the address (bit 0x01 cleared)
+  * 3: subaddress length (0..3)
+  * 4: subaddress byte 0 (or only byte for subaddress length 1)
+  * 5: subaddress byte 1
+  * 6: subaddress byte 2
+  * 7: combined address (device address for combined mode data phase)
+  * 8: data length
+  *
+  * The transfer types are the same good old Apple ones it seems,
+  * that is:
+  *   - 0x00: Simple transfer
+  *   - 0x01: Subaddress transfer (addr write + data tx, no restart)
+  *   - 0x02: Combined transfer (addr write + restart + data tx)
+  *
+  * This is then followed by actual data for a write.
+  *
+  * At this point, the OF driver seems to have a limitation on transfer
+  * sizes of 0xd bytes on reads and 0x5 bytes on writes. I do not know
+  * wether this is just an OF limit due to some temporary buffer size
+  * or if this is an SMU imposed limit. This driver has the same limitation
+  * for now as I use a 0x10 bytes temporary buffer as well
+  *
+  * Once that is completed, a response is expected from the SMU. This is
+  * obtained via a command of type 0x9a with a length of 1 byte containing
+  * 0 as the data byte. OF also fills the rest of the data buffer with 0xff's
+  * though I can't tell yet if this is actually necessary. Once this command
+  * is complete, at this point, all I can tell is what OF does. OF tests
+  * byte 0 of the reply:
+  *   - on read, 0xfe or 0xfc : bus is busy, wait (see below) or nak ?
+  *   - on read, 0x00 or 0x01 : reply is in buffer (after the byte 0)
+  *   - on write, < 0 -> failure (immediate exit)
+  *   - else, OF just exists (without error, weird)
+  *
+  * So on read, there is this wait-for-busy thing when getting a 0xfc or
+  * 0xfe result. OF does a loop of up to 64 retries, waiting 20ms and
+  * doing the above again until either the retries expire or the result
+  * is no longer 0xfe or 0xfc
+  *
+  * The Darwin I2C driver is less subtle though. On any non-success status
+  * from the response command, it waits 5ms and tries again up to 20 times,
+  * it doesn't differenciate between fatal errors or "busy" status.
+  *
+  * This driver provides an asynchronous paramblock based i2c command
+  * interface to be used either directly by low level code or by a higher
+  * level driver interfacing to the linux i2c layer. The current
+  * implementation of this relies on working timers & timer interrupts
+  * though, so be careful of calling context for now. This may be "fixed"
+  * in the future by adding a polling facility.

+ * wmb() prevents stores being reordered across this point.
+ * read_barrier_depends() prevents data-dependent loads being reordered
+ *      across this point (nop on PPC).
+ *
+ * We have to use the sync instructions for mb(), since lwsync doesn't
+ * order loads with respect to previous stores.  Lwsync is fine for
+ * rmb(), though. Note that rmb() actually uses a sync on 32-bit
+ * architectures.
+ *
+ * For wmb(), we use sync since wmb is used in drivers to order
+ * stores to system memory with respect to writes to the device.
+ * However, smp_wmb() can be a lighter-weight lwsync or eieio barrier
+ * on SMP since it is only used to order updates to system memory.

+/* My understanding of UniNorth AGP as of UniNorth rev 1.0x,
+ * revision 1.5 (x4 AGP) may need further changes.
+ *
+ * AGP_BASE register contains the base address of the AGP aperture on
+ * the AGP bus. It doesn't seem to be visible to the CPU as of UniNorth 1.x,
+ * even if decoding of this address range is enabled in the address select
+ * register. Apparently, the only supported bases are 256Mb multiples
+ * (high 4 bits of that register).
+ *
+ * GART_BASE register appear to contain the physical address of the GART
+ * in system memory in the high address bits (page aligned), and the
+ * GART size in the low order bits (number of GART pages)
+ *
+ * The GART format itself is one 32bits word per physical memory page.
+ * This word contains, in little-endian format (!!!), the physical address
+ * of the page in the high bits, and what appears to be an "enable" bit
+ * in the LSB bit (0) that must be set to 1 when the entry is valid.
+ *
+ * Obviously, the GART is not cache coherent and so any change to it
+ * must be flushed to memory (or maybe just make the GART space non
+ * cachable). AGP memory itself doens't seem to be cache coherent neither.
+ *
+ * In order to invalidate the GART (which is probably necessary to inval
+ * the bridge internal TLBs), the following sequence has to be written,
+ * in order, to the GART_CTRL register:
+ *
+ *   UNI_N_CFG_GART_ENABLE | UNI_N_CFG_GART_INVAL
+ *   UNI_N_CFG_GART_ENABLE
+ *   UNI_N_CFG_GART_ENABLE | UNI_N_CFG_GART_2xRESET
+ *   UNI_N_CFG_GART_ENABLE
+ *
+ * As far as AGP "features" are concerned, it looks like fast write may
+ * not be supported but this has to be confirmed.
+ *
+ * Turning on AGP seem to require a double invalidate operation, one before
+ * setting the AGP command register, on after.
+ *
+ * Turning off AGP seems to require the following sequence: first wait
+ * for the AGP to be idle by reading the internal status register, then
+ * write in that order to the GART_CTRL register:
+ *
+ *   UNI_N_CFG_GART_ENABLE | UNI_N_CFG_GART_INVAL
+ *   0
+ *   UNI_N_CFG_GART_2xRESET

+ * Core file format: The core file is written in such a way that gdb
+ * can understand it and provide useful information to the user (under
+ * linux we use the `trad-core' bfd, NOT the osf-core).  The file contents
+ * are as follows:
+ *
+ *  upage: 1 page consisting of a user struct that tells gdb
+ *      what is present in the file.  Directly after this is a
+ *      copy of the task_struct, which is currently not used by gdb,
+ *      but it may come in handy at some point.  All of the registers
+ *      are stored as part of the upage.  The upage should always be
+ *      only one page long.
+ *  data: The data segment follows next.  We use current->end_text to
+ *      current->brk to pick up all of the user variables, plus any memory
+ *      that may have been sbrk'ed.  No attempt is made to determine if a
+ *      page is demand-zero or if a page is totally unused, we just cover
+ *      the entire range.  All of the addresses are rounded in such a way
+ *      that an integral number of pages is written.
+ *  stack: We need the stack information in order to get a meaningful
+ *      backtrace.  We need to write the data from usp to
+ *      current->start_stack, so we round each of these in order to be able
+ *      to write an integer number of pages.
