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 ].

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..

af5ca3f4ec Driver core: change sysdev classes to use dynamic kobject names 
All kobjects require a dynamically allocated name now. We no longer
need to keep track if the name is statically assigned, we can just
unconditionally free() all kobject names on cleanup.

38a382ae5d Kobject: convert arch/* from kobject_unregister() to kobject_put() 
There is no need for kobject_unregister() anymore, thanks to Kay's
kobject cleanup changes, so replace all instances of it with
kobject_put().

d48b335256 Kobject: change arch/sh/kernel/cpu/sh4/sq.c to use kobject_init_and_add 
Stop using kobject_register, as this way we can control the sending of
the uevent properly, after everything is properly initialized.

b0d98dc504 sh: Support PCI IO access of SH7780 base boards. 
The IO access of PCI is not supported in R7780RP and the MS7780SE
board now. The support of the IO access mode of e100 and a lot of IDE
chips becomes possible by fixing the code.
