7a2eacb759 sh: Provide a 29/32-bit physical hint for bootloaders. 
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 ].

mem= can't be used to grow the size of kernel memory, so provide a
warning to that effect.

a8f67f4b4d sh: Add SH7263 CPU support. 
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..

1cb80fcfe2 sh: Merge sh and sh64 module.c. 
This is trivial, in that they're both effectively the same for the base
relocations anyways. SH-5 doesn't need the unaligned bits, and has a
few extra relocations, which are never hit on non-SH5 parts.
