Commit 1c957036bbd912322793da676d05e169abf24782 breaks booting on OMAP2; it causes the SRAM to be mapped on top of the L4 interconnect. This causes the system to hang early in boot in omap_map_sram() during the TLB flush. Fix by moving SRAM elsewhere in the memory map. Reported by Jarkko Nikula <jarkko.nikula@xxxxxxxxx>. This patch is a collaboration with Tony Lindgren <tony@xxxxxxxxxxx> and Kevin Hilman <khilman@xxxxxxxxxxxxxxxxxxx>. Boot-tested on 2430SDP (by Paul) and N810 (by Jarkko).
