> From: Jean Pihet <j-pihet at ti.com>
>
> The SRAM PA addresses are locally defined and used at
> different places, i.e. SRAM management code and idle sleep code.
>
> The macros are now defined at a centralized place, for
> easier maintenance.
>
> Tested on N900 and Beagleboard with full RET and OFF modes,
> using cpuidle and suspend.

Though not directly related to the patch, information sake: the PUB
physical address on a GP device != public SRAM address on a HS/EMU
device - in theory PPA can reconfigure how much is available for a
HS/EMU device here.
