Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+ * NOTES about DMA transfers:
+ *
+ *  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.

+ *             associated structure pointed to by "additions", see
+ *             how it's done for the EMAC driver.
+ * @paddr:     Device physical address (may not mean anything...)
+ * @irq:       Interrupt line for this device (TODO: think about making

+ * @pm:        Currently, contains the bitmask in CPMFR DCR for the device
+ * @additions: Optionally points to a function specific structure

+ * The PowerPC MPC8xx uses a TLB with hardware assisted, software tablewalk.

+ * Mx_CTR.PPCS = 0, and MD_CTR.TWAM = 1.  The level 2 descriptor has
+ * additional page protection (when Mx_CTR.PPCS = 1) that allows TLB hit
+ * based upon user/super access.  The TLB does not have accessed nor write
+ * protect.  We assume that if the TLB get loaded with an entry it is
+ * accessed, and overload the changed bit for write protect.  We use
+ * two bits in the software pte that are supposed to be set to zero in
+ * the TLB entry (24 and 25) for these indicators.  Although the level 1
+ * descriptor contains the guarded and writethrough/copyback bits, we can
+ * set these at the page level since they get copied from the Mx_TWC
+ * register when the TLB entry is loaded.  We will use bit 27 for guard, since
+ * that is where it exists in the MD_TWC, and bit 26 for writethrough.
+ * These will get masked from the level 2 descriptor at TLB load time, and
+ * copied to the MD_TWC before it gets loaded.
+ * Large page sizes added.  We currently support two sizes, 4K and 8M.
+ * This also allows a TLB hander optimization because we can directly
+ * load the PMD into MD_TWC.  The 8M pages are only used for kernel

+/* 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
+ *   0

+ *	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

+ *	that an integral number of pages is written.
