2008-01-28sh: GUSA atomic rollback support.Stuart Menefy
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.

2008-01-28sh: Provide a 29/32-bit physical hint for bootloaders.Stuart Menefy
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 ].

2008-01-28sh: Add SH7263 CPU support.Paul Mundt
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.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
