5b80234435 [ARM] 3490/1: i.MX: move uart resources to board files
Patch from Sascha Hauer

This patch moves the i.MX uart resources and the gpio pin setup to the
board files. This allows the boards to decide how many internal uarts
are connected to the outside world and whether they use rts/cts or
not.

76bbb00288 [ARM] 3487/1: IXP4xx: Support non-PCI systems
Patch from Deepak Saxena

This patch allows for the addition of IXP4xx systems that do not make
use of the PCI interface by moving the CONFIG_PCI symbol selection to
be platform-specific instead of for all of IXP4xx. If at least one machine
with PCI support is built, the PCI code will be compiled in, but when
building !PCI, this will drastically shrink the kernel size.

cd95842ca0 [ARM] 3486/1: Mark memory as clobbered by the ARM _syscallX() macros
Patch from Markus Gutschke

In order to prevent gcc from making incorrect optimizations, all asm()
statements that define system calls should report memory as
clobbered. Recent versions of the headers for i386 have been changed
accordingly, but the ARM headers are still defective.

c80d79d746 [PATCH] Configurable NODES_SHIFT
Current implementations define NODES_SHIFT in include/asm-xxx/numnodes.h for
each arch.  Its definition is sometimes configurable.  Indeed, ia64 defines 5
NODES_SHIFT values in the current git tree.  But it looks a bit messy.

SGI-SN2(ia64) system requires 1024 nodes, and the number of nodes already has
been changeable by config.  Suitable node's number may be changed in the
future even if it is other architecture.  So, I wrote configurable node's
number.

This patch set defines just default value for each arch which needs multi
nodes except ia64.  But, it is easy to change to configurable if necessary.

On ia64 the number of nodes can be already configured in generic ia64 and SN2
config.  But, NODES_SHIFT is defined for DIG64 and HP'S machine too.  So, I
changed it so that all platforms can be configured via CONFIG_NODES_SHIFT.  It
would be simpler.

9323557975 [ARM] 3459/1: ixp23xx: fix debug serial macros for big-endian operation
Patch from Lennert Buytenhek

The debug-8250 macros do byte accesses, which means that if we're in
big-endian mode, we need to logically OR the UART address with 3, as
the LSB byte lane (where UART data and status is transferred) has the
highest byte address in the word when we are in big-endian mode.

It's unclear why this problem didn't surface earlier.

0da323505f [ARM] arm's arch_local_page_offset() fix against 2.6.17-rc1
This patch fixes arch_local_page_offset(pfn,nid) in arm.
This new one (added by unify_pfn_to_page patches) is obviously buggy.

This macro calculate page offset in a node.

Note: about LOCAL_MAP_NR()
comment in arm's sub-archs says...

 /*
  * Given a kaddr, LOCAL_MAP_NR finds the owning node of the memory
  * and returns the index corresponding to the appropriate page in the
  * node's mem_map.
  */

but LOCAL_MAP_NR() is designed to be able to take both paddr and kaddr.
In this case, paddr is better.

56ca904053 [ARM] 3457/1: i.MX: SD/MMC support for i.MX/MX1
Patch from Pavel Pisa

This patch adds support of i.MX/MX1 SD/MMC controller.
It has been significantly redesigned from the original Sascha Hauer's
version to support scatter-gather DMA, to conform to latest Pierre Ossman's
and Russell King's MMC-SD Linux 2.6.x infrastructure.
The handling of all events has been moved to the softirq context
and is designed with no busy-looping in mind. Unfortunately
some controller bugs has to be overcome by limited looping
about 2-20 usec but these are observed only for initial card
recognition phase.

There are still some missing/missed IRQs problems under heavy load.
Help of somebody with access to the full SDHC design information
is probably necessary.

Regenerated against 2.6.16-git-060402 to solve clash with other patches.

23759dc643 [ARM] 3439/2: xsc3: add I/O coherency support
Patch from Lennert Buytenhek

This patch adds support for the I/O coherent cache available on the
xsc3.  The approach is to provide a simple API to determine whether the
chipset supports coherency by calling arch_is_coherent() and then
setting the appropriate system memory PTE and PMD bits.  In addition,
we call this API on dma_alloc_coherent() and dma_map_single() calls.
A generic version exists that will compile out all the coherency-related
code that is not needed on the majority of ARM systems.

Note that we do not check for coherency in the dma_alloc_writecombine()
function as that still requires a special PTE setting.  We also don't
touch dma_mmap_coherent() as that is a special ARM-only API that is by
definition only used on non-coherent system.

Create ixp23xx_pci_common_init(), move the common initialisation bits
there, and have this function called from both the PCI master and the
PCI slave init path.

fd88dd740a [ARM] 3434/1: pxa i2s amsl define
Patch from Marc-Andre Hebert

The error concerns a bit mask define for the AMSL bit of the SACR1 register in the 2.6 kernel tree. The AMSL is bit 0 and it was defined as so in the 2.4 kernel tree but it is inccorrectly set as bit 1 (a reserved bit) in the 2.6 kernel tree.

c471307437 [ARM] 3388/1: ixp23xx: add core ixp23xx support
Patch from Lennert Buytenhek

This patch adds support for the Intel ixp23xx series of CPUs.  The
ixp23xx is an XSC3 based CPU with 512K of L2 cache, a 64bit 66MHz PCI
interface, two DDR RAM interfaces, QDR RAM interfaces, two gigabit
MACs, two 10/100 MACs, expansion bus, four microengines, a Media and
Switch Fabric unit almost identical to the one on the ixp2400, two
xscale (8250ish) UARTs and a bunch of other stuff.

This patch adds the core ixp23xx support code, and support for the
ADI Engineering Roadrunner, Intel IXDP2351, and IP Fabrics Double
Espresso platforms.

23bdf86aa0 [ARM] 3377/2: add support for intel xsc3 core
Patch from Lennert Buytenhek

This patch adds support for the new XScale v3 core.  This is an
ARMv5 ISA core with the following additions:

- L2 cache
- I/O coherency support (on select chipsets)
- Low-Locality Reference cache attributes (replaces mini-cache)
- Supersections (v6 compatible)
- 36-bit addressing (v6 compatible)
- Single instruction cache line clean/invalidate
- LRU cache replacement (vs round-robin)

I attempted to merge the XSC3 support into proc-xscale.S, but XSC3
cores have separate errata and have to handle things like L2, so it
is simpler to keep it separate.

L2 cache support is currently a build option because the L2 enable
bit must be set before we enable the MMU and there is no easy way to
capture command line parameters at this point.

There are still optimizations that can be done such as using LLR for
copypage (in theory using the exisiting mini-cache code) but those
can be addressed down the road.

c9b4470e2d [ARM] 3414/1: ep93xx: reset ethernet controller before uncompressing
Patch from Lennert Buytenhek

The Redboot version that cirrus supplies for the cirrus ep93xx doesn't
turn off DMA from the ethernet MAC before jumping to linux, which means
that we might end up with bits of RX status and packet data scribbled
over the uncompressed kernel image.

Work around this by resetting the ethernet MAC before we uncompress.

We don't usually work around bootloader bugs, but considering that the
large majority of ep93xx boards out there have this problem, I figured
this it was justified in this case.
