does the following patch fix the problem for you?

Commit 1c957036bbd912322793da676d05e169abf24782 breaks booting on
OMAP2; the SRAM is mapped on top of the L4 interconnect. This causes
the system to hang early in boot in omap_map_sram() during a 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>.
Tested on 2430SDP.
