If you are using a GCC >= 4.7 this is most likely the problem that GCC
now produces hardware unaligned access instructions on ARMv7 by default.
Unfortunately the EHCI spec has placed one of the registers at an
unaligned offset. Barebox traps the processor when hitting an unaligned
access in hardware.
Thanks for the heads up, I'll make sure we resolve this problem before
this patchset goes in.
Regards,
Lucas
