From: Vishwanath BS <[email protected]> For historical reasons the OMAP3 sleep code is run from SRAM. This code can run from DDR which provides better performance and leaves the SRAM available for other uses.
Tested on ZOOM3, OMAP3EVM, Beagleboard, n900 with full RET and OFF modes. Signed-off-by: Vishwanath BS <[email protected]> Cc: Kevin Hillman <[email protected]> Changed the commit comments.
