From b4b36fd94e4ca99b3258ff24c2c58cdde67085e0 Mon Sep 17 00:00:00 2001 From: Jean Pihet Date: Sat, 18 Dec 2010 16:44:42 +0100 Subject: OMAP2+: use global values for the SRAM PA addresses 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.
