da591937ba [ARM] 5280/1: pxa: prepare cm-x2xx.c and cm-x2xx-pci.[ch] for addition of CM-X255
- Change CM-X255 and CM-X270 common function prefix from cmx270 to cmx2xx
- Split cmx2xx_init to common and CM-X270-specific parts
- Use dynamic assignement for DM9000 resources and led GPIOs.

446b097a42 [ARM] 5293/1: ep93xx: add defines for external chipselects
This patch adds defines for the external chipselect physical base
addresses available with the EP93xx. These are meant to be used
in the platform init code.

In addition, documentation about the synchronous/asynchronous boot
modes for the EP93xx and a reference to errata about issues with
synchronous booting has been added.

a0a08fdca5 [ARM] 5273/2: ep93xx: move ethernet support into core.c
All EP93xx based systems can support Ethernet. This patch moves
the platform_device setup from the various board support files
into the core support file. The Ethernet driver data still remains
in the individual platform setup files to allow specific platform
configuration.

This also adds Ethernet support to the edb9302, edb9312, and
edb9315 platforms.

92e88aa7fb [ARM] 5276/1: ep93xx: allow selecting UART for early kernel messages
Currently on the EP93xx platform early kernel messages go to UART1.
Since this UART is the only one that has modem control signals it
might be used for another purpose and it is undesirable for those
messages to appear. This patch allows one of the other UARTs to be
selected in the kernel configuration. It is assumed that the
bootloader has configured and initialized the UART since this was the
previous assumption.

125ab12acf [ARM] dma: fix dmabounce dma_sync_xxx() implementations
The dmabounce dma_sync_xxx() implementation have been broken for
quite some time; they all copy data between the DMA buffer and
the CPU visible buffer no irrespective of the change of ownership.
(IOW, a DMA_FROM_DEVICE mapping copies data from the DMA buffer
to the CPU buffer during a call to dma_sync_single_for_device().)

Fix it by getting rid of sync_single(), moving the contents into
the recently created dmabounce_sync_for_xxx() functions and adjusting
appropriately.

This also makes it possible to properly support the DMA range sync
functions.

d7161a6534 kgdb, x86, arm, mips, powerpc: ignore user space single stepping
On the x86 arch, user space single step exceptions should be ignored
if they occur in the kernel space, such as ptrace stepping through a
system call.

First check if it is kgdb that is executing a single step, then ensure
it is not an accidental traversal into the user space, while in kgdb,
any other time the TIF_SINGLESTEP is set, kgdb should ignore the
exception.

On x86, arm, mips and powerpc, the kgdb_contthread usage was
inconsistent with the way single stepping is implemented in the kgdb
core.  The arch specific stub should always set the
kgdb_cpu_doing_single_step correctly if it is single stepping.  This
allows kgdb to correctly process an instruction steps if ptrace
happens to be requesting an instruction step over a system call.

c0e9587841 [ARM] Introduce new bitmask based cache type macros
Rather than trying to (inaccurately) decode the cache type from the
registers each time we need to decide what type of cache we have,
use a bitmask initialized early during boot.

Since the setup is a one-off initialization, we can be a little more
clever and take account of the CPU architecture as well.

Note that we continue to achieve the compactness on optimised kernels
by forcing tests to always-false or always-true as appropriate, thereby
allowing the compiler to do build-time code elimination.

90f1e08478 [ARM] Remove cache type printks
The cache type register found in ARMv5 and later CPUs changes format
and meaning depending on the CPU architecture version.  Currently,
this code:
a) doesn't work for everything - Xscale's are identified as
   'unknown 5'.
b) is not able to tell whether the caches are VIVT or VIPT from the
   cache type.
c) prints rubbish on some ARMv6 and ARMv7+ CPUs.

The two solutions to this are:
1. Add yet more code to decode and print the various different register
   formats.
2. Remove the code altogther.

The code only exists to decode and print the cache parameters.
Increasing the complexity of it just for the sake of a few prinks
isn't worth it.
