Make all OMAP DT only platforms (am33xx, am43xx, omap4 and omap5) use
drivers/misc/sram.cdriver instead of the omap internal implementation for SRAM handling.Rajendra Nayak (2):

Really nice to see the SRAM code getting moved now. Thanks a lot Rajendra.
- The
sram_init()seems to be the post core init call. Hope this is not a problem for SDRC init which needs to have SRAM ready to update the DDR parameters.
It should be fine given its needed only during core dvfs. Besides drivers/misc/sram.c is useful only on DT platforms, so for now OMAP2/3 continue to use the omap specific sram handling.
