PATCH 1/1 Fix alignment error on ARM for modules

In reply to Kyungmin Park

Fix alignment fault on ARM when running modules. With out an explicit linker file gcc4.2.1 will half word align __bss_start's value. The word dereference will crash hello_world.

[U-Boot-Users] Quick OMAP2420 update for anyone interested.

Hi,

I'll attach a zip of a quick update for h4-2420 which I did against git just now. It needs more work to merge but at least works. Its probably on the edge for size. A 2430 merge and more of a fix up could come later.

Regards,
Richard W.
