following:
From: Jean Pihet <j-pihet@xxxxxx>
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.
