Dear Aneesh V,
Enable -march=armv7-a for armv7 platforms if the tool-chain
supports it. This in turn results in Thumb-2 code generated
for these platforms if CONFIG_SYS_THUMB_BUILD is enabled.

For some reason, this patch breaks USB EHCI on mx51 efika boards. The board just
freezes instead of detecting USB devices. Reverting this patch fixes the issue.
Note I use gcc 4.7.1 (!), might be compiler issue?
Tom, can you try on one of your beagle-dogs please? :)
Just for your information,
I doubt unaligned access causes this problem.
My investigation is here,

My patch
[PATCH] arm: armv7: add compile option -mno-unaligned-access if available

This makes sense. You might want to try this patch. Also, to be sure
that it's nothing to do with Thumb you can make sure you are not
enabling CONFIG_SYS_THUMB_BUILD.
best regards,
Aneesh
