Adds functions to read and write IXP4xx "feature" (aka "fuse")
bits, containing information about available/enabled CPU features.
The uncompress.h included by boot/compressed/misc.c resides in
a different space than rest of the kernel and thus can't use
asm/hardware.h (including asm/arch/cpu.h - which, in turn, may use
EXPORTed symbol "processor_id").

Add Intel KIXRP435 Reference Platform based on IXP43x processor.
Fixed after review : access to cp15 removed in identification functions,
used access to global processor_id instead

This fixs address defines for IXP4XX_NPE[ABC]_BASE_VIRT.
They are defined as (IXP4XX_PERIPHERAL_BASE_PHYS + 0x[678]000) now,
but they should be defined as (IXP4XX_PERIPHERAL_BASE_VIRT + 0x[678]000). Note PHYS vs VIRT in IXP4XX_PERIPHERAL_BASE...

Patch from Kenneth Tan
Defining IXP46X peripheral devices memory mapping definitions that have
been missed out:
o Peripheral virtual base address is being adjusted to allow more headroom to add extra peripheral device addresses
o Peripheral size is being increased to address the above needs
o Virtual address of expansion bus and PCI configuration register needs to be adjusted as new peripheral device memory space is overlapping with their virtual address space

Patch from Deepak Saxena
Current IXP4xx debug macros do not work in the small window between
the MMU being enabled and the call to map_io() b/c the standard
peripheral mapping is not properly setup for use with the low-level
debug code. This patch creates a new section-aligned mapping for the
UART specifically for use with the debug macros.

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!
