Hello All,

I have just unexpectedly found an old Beagleboard B7 in my closet and tried to compile the current U-Boot master branch for it. Appears that it is broken since almost 2 years ago:

And after trying to narrow it down, looks like the failure happens in the prcm_init() function from 'arch/arm/mach-omap2/omap3/clock.c' when it is compiled as Thumb2. At least the SPL can successfully boot after the following change (GCC6 is needed for this pragma):

Good job sorting this out. I think it might be best to just disable Thumb on beagleboard.
