fa3e686a34 [ARM] 3601/1: i.MX/MX1 DMA error handling for signaled channels only
Patch from Pavel Pisa

There has been bug, that dma_err_handler() touches even
channels not signaling error condition.

Problem noticed by Andrea Paterniani.

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.

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.

999331af45 [ARM] 3444/1: i.MX: Scatter-gather DMA emulation for i.MX/MX1
Patch from Pavel Pisa

This patch contains simplified set of changes to add scatter-gather
emulation capability into MX1 DMA support. The result should
be still usable for next combination of DMA transfers
  Statter-Gather/linear/2D/FIFO to linear/2D/FIFO and
  linear/2D/FIFO to Statter-Gather/2D/FIFO
The patch corrects channel priority allocation to be compatible
with MX1 hardware implementation.
Previous code has not been adapted from its PXA original.

411ef7f4cf [ARM] Remove asm/arch/irq.h
asm/arch/irq.h used to be included from asm/irq.h, but was removed
from the ARM kernel a long time ago.  Consequently, the contents
of asm/arch/irq.h (which mostly contain a definition for fixup_irq())
have not been used.  Hence, remove asm/arch/irq.h.

Some machine support files incorrectly included this file, making
little or no use of the contents.  Move the contents to a local
include file, and remove those include statements as well.

95ba9fb06b [ARM] Remove definition of MAX_DMA_CHANNELS to zero
Since we now only build arch/arm/kernel/dma.c on machine types
which set ISA_DMA_API, we don't need to define MAX_DMA_CHANNELS
to 0 to indicate this - this definition becomes superfluous.

78ff18a412 [ARM] Cleanup ARM includes
arch/arm/kernel/entry-armv.S has contained a comment suggesting
that asm/hardware.h and asm/arch/irqs.h should be moved into the
asm/arch/entry-macro.S include.  So move the includes to these
two files as required.

Add missing includes (asm/hardware.h, asm/io.h) to asm/arch/system.h
includes which use those facilities, and remove asm/io.h from
kernel/process.c.

Remove other unnecessary includes from arch/arm/kernel, arch/arm/mm
and arch/arm/mach-footbridge.

f09b997999 [ARM] 3060/1: allow constants found in asm/memory.h to be used in asm code
Patch from Nicolas Pitre

This patch allows for assorted type of cleanups by letting assembly code
use the same set of defines for constant values and avoid duplicated
definitions that might not always be in sync, or that might simply be
confusing due to the different names for the same thing.

Patch from Sascha Hauer

Current implementation of imx_gpio_mode does not allow to
configure all alternate routing possibilities of the i.MX. With
this patch every bit in the gpio setup registers has a
corresponding bit in the gpio_mode parameter, so every routing
should be possible now.

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!
