From: Jean Pihet <j-pihet@xxxxxx> The SRAM PA addresses are locally defined and used in both the SRAM management code and the idle sleep code. A global macro defines the values at a centralized place, for easier maintenance. Tested on N900 and Beagleboard with full RET and OFF modes, using cpuidle and suspend.
