Krzysztof Hałasa 0a07232ff6 IXP4xx: workaround for PCI prefetch problems near 64 MB boundary.
Map unused registers at the end of DMA region at 64 MB to allow PCI masters
to cross the boundary when prefetching data from SDRAM.

Russell King be50972935 [ARM] Remove asm/hardware.h, use asm/arch/hardware.h instead
Remove includes of asm/hardware.h in addition to asm/arch/hardware.h.
Then, since asm/hardware.h only exists to include asm/arch/hardware.h,
update everything to directly include asm/arch/hardware.h and remove
asm/hardware.h.

Rod Whitby 313cbb5519 [ARM] 3218/1: PAGE_SHIFT undeclared in arch-ixp4xx/memory.h (adjust_zones moved out of line)
Patch from Rod Whitby

PAGE_SHIFT is undeclared in include/asm-arm/arch-ixp4xx/memory.h, identified by the following kernel compilation error:

CC [M] sound/core/memory.o
In file included from include/asm/memory.h:27,

include/asm/arch/memory.h: In function `__arch_adjust_zones':
include/asm/arch/memory.h:28: error: `PAGE_SHIFT' undeclared (first use
in this function)

This patch replaces my previous attempt at fixing this problem (Patch 3214/1) and is based on the following feedback:

I have moved the function out of line into arch/arm/mach-ixp4xx/common-pci.c as suggested.

Alessandro Zummo 84613387cb [ARM] 3089/1: ixp4xx AHB/PCI endianness fix
Patch from Alessandro Zummo

  This patch fixes AHB/PCI endianness problems when the
 processor is in little-endian mode.

 The patch configures the CSR register closely following the directives
 in [1], paragraph 4.1, page 19.

 According to the considerations in [1], page 11, while the AHB bus
 supports both endian modes, on the IXP4XX it always uses big-endian.

 The PCI bus is connected to the South AHB. A wrong setting in the CSR
 register will thus cause a malfunctional PCI bus.

 A schematic diagram of the bus interconnections on the IXP4XX
 can be found in [1], page 18.

 The patch has been verified to work on the NSLU2 in
 both LE and BE modes.

 The author is Peter Korsgaard.

Deepak Saxena 450008b5a6 [PATCH] ARM: 2792/1: IXP4xx iomap API implementation
Patch from Deepak Saxena

This patch implements the iomap API for Intel IXP4xx NPU systems.
We need to implement our own version of the API functions b/c of the
PCI hostbridge does not provide the capability to map PCI I/O space
into the CPU's physical memory space. In addition, if a system has
more than 64M of PCI memory mapped BARs, PCI memory must also be
accessed indirectly.  This patch changes the assignment of PCI I/O
resources to fall into to 0x0000:0xffff range so that we can trap
I/O areas in our ioread/iowrite macros.

Linus Torvalds 1da177e4c3 Linux-2.6.12-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!
