With ARCH_HAS_DECOMP_WDOG removed from arch/arm/boot/compressed/decompress.c,
all the arch_decomp_wdog() definition at platform level is unneeded.
Remmove it.

In the earlier sweeping changes, the ux500 uncompress.h file was missed
because other problems were hiding this one.

Without this patch, building u8500_defconfig results in:

In file included from arch/arm/boot/compressed/misc.c:33:0:
arch/arm/mach-ux500/include/mach/uncompress.h: In function 'putc':

This platform has been obsoleted and was only available inside of
ST-Ericsson, no users of this code are left in the world. This
deletes the core U5500 support entirely in the same manner as the
obsoleted U8500 silicon was previously deleted.

The cpu_is_u5500() macros that can read out the CPU ID is left
until the next kernel cycle, this makes it possible to merge
deletion of dependent drivers without breakage.

This also has the upside of removing the mailbox driver which was
our only driver that was outside the drivers/* hiearchy, now the
machine directory only handles machines and nothing else.

To be able to relocate the .bss section at run time independently from
the rest of the code, we must make sure that no GOTOFF relocations are
used with .bss symbols.  This usually means that no global variables can
be marked static unless they're also const.

Let's remove the static qualifier from current offenders, or turn them
into const variables when possible.  Next commit will ensure the build
fails if one of those is reintroduced due to otherwise enforced coding
standards for the kernel.

The HREFv60 variant of the MOP500 family of boards remove the
external GPIO expander and route these pins back to some of the
readily available internal GPIO pins instead.

Based on a patch by Bibek Basu <bibek.basu@stericsson.com> for
an internal kernel version.

The uncompress code for zImage uses the UART to print status messages,
this was hard coded to use UART2 for the U8500 platform. This patch
checks at run time which platform it is run on. U5500 uses UART0 as
console UART.

Don't use writeb() in uncompress.h, to avoid the following build errors
when the "Add barriers to the I/O accessors" series is applied.  Use
__raw_writeb() instead.

Adds core support for the ST-Ericsson U8500
platform. It supports memory mappings, binds to
the existing modules like GIC, SCU, TWD and
local timers and sets up the infrastructure for
the secondary core.
