This patch removes redundant irq handling code together with unused
consistent alloc code. R2D uart setup code is changed to use
sm501-regs.h and unused header files are removed.

This patch adds timings to drive a Sharp LQ104V1DG21 lcd panel that can
be hooked up to R2D-1 or R2D-PLUS. The sm501fb driver should leave the
pins FPEN and VBIASEN alone, and this patch instructs the driver to do
so by not setting flags flags for these pins.
This patch works best together with the patch posted to the
linux-fbdev-devel list "sm501fb: control panel pin usage with platform
data flags", but this patch can be merged independently.

This patch removes interrupt priority tables from the intc code.
Optimal priority assignment varies with embedded application anyway,
so keeping the interrupt priority tables together with cpu-specific
code doesn't make sense.
The function intc_set_priority() should be used instead to set the
desired interrupt priority level.

This patch provides a correct value for CONFIG_SH_PCLK_FREQ for the
SH7712 solution engine when used with the board's default factory
settings. This results in the board running at its maximum CPU clock
rate (200 MHz).

This adds in the L1I/L1D/L2 cache shape support to their respective
entries in the ELF auxvt, based on the Alpha implementation. We use
this on the userspace libc side for calculating a tightly packed
SHMLBA amongst other things.

This patch changes the uImage target so that it generates a wrapped
compressed vmlinux, rather than a wrapped zImage. The previous version
matched the ARM, this version matches the PPC. However I would question
how useful a self decompressing image is with a boot loader which does
decompression, so I think this is more useful. I also feel it matches
the descrition in the help text ("Compressed kernel image") better.

This saves us from having to use kmalloc() for the fixmap entries,
which is needed early for the uncached fixmap.

Presently most of the 29-bit physical parts do P1/P2 segmentation
with a 1:1 cached/uncached mapping, jumping between the two to
control the caching behaviour. This provides the basic infrastructure
to maintain this behaviour on 32-bit physical parts that don't map
P1/P2 at all, using a shiny new linker section and corresponding
fixmap entry.

This implements kernel-level atomic rollback built on top of gUSA,
as an alternative non-IRQ based atomicity method. This is generally
a faster method for platforms that are lacking the LL/SC pairs that
SH-4A and later use, and is only supportable on legacy cores.

Shoves a magic word in to the empty_zero_page section for the
bootloader to work out whether to start the kernel in 29-bit
or 32-bit mode.
[ Renesas CPUs already take care of the initial PMB mappings entirely
in hardware and decide on 29-bit/32-bit physical depending on which
pin powered up the CPU, so this is mostly for ST parts. -- PFM ].

This adds support for the SH7263 (SH-2A) CPU.
This particular CPU is a superset of SH7203, adding some additional
peripheral blocks and hooking up additional (reserved on SH7203)
vectors in the INTC block.
No visibly nasty surprises, yet..

This was using the absolute path, which was confusing the make target.
