Hi, Noticed an interesting behavior where adding a dcache flush kernel boot fail due to unaligned-accesses seems to go away. Full details: http://pastebin.com/kVBRWsbE Without dcache flush being added to my uenvcmd:
Kernel image @ 0x80200000 [ 0x000000 - 0x3e2690 ] data abort
MAYBE you should read doc/README.arm-unaligned-accesses

With dcache flush being added to my uenvcmd: complete boot
I think something of the form was highlighted here: http://marc.info/?l=u-boot&m=137276534624656&w=2
Not sure if there was any conclusion to the effect.
A quick tag bisect attempt was'nt too useful either.
