Looks like for you " is_sram_locked" function is failing. There was a patch
in my series from Vikram which was fixing this API.

Do you have this patch applied when you are trying this out ?

Well it looks like this only happens on linux-next (was using
next-20101001 version) with this defconfig:
http://notaz.gp2x.de/misc/pnd/config_next_101001_2

this has yours and Vikram's patch you mentioned in. Using
omap2plus_defconfig on linux-next or this "bad" defconfig on
linux-omap boots fine, strange.
