[U-Boot] Crash in env_relocate_spec() of env_mmc.c

[Steve Sakoman]

I've been attempting to get the OMAP4 boards working post the ARM
relocation changes.

Panda was simple.  The OMAP4430SDP is proving to be more challenging,
as it freezes after printing the DRAM size message.

Adding a few printfs revealed that the crash occurs in env_mmc.c's
env_relocate_spec() routine.

Has anyone else run into this issue?  Any advice?
