OK, but why the nandecc switching around?  On omap3_beagle _now_ (and
for a year or two, but a change from long ago) we do nandecc hw for MLO
and U-Boot and get the same 1bit ECC scheme the kernel uses too.  I bet
the problem is that SPL is loading and expecting the HW scheme, but you
wrote in the SW scheme...
