Also, can you guys also please do a patch to move plat/usb.h to
include/linux/platform_data/usb-omap.h that only contains
platform data? The init functions should be in local usb.h under
arch/arm/*omap*/*. Then also please remove the cpu_is_omap usage
from drivers/mfd/omap-usb-host.c if not done already.

These are needed to make plat/cpu.h local to mach-omap*
for the ARM common zImage support.

Thanks,

Tony
