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
pc : [<9ff6f6b4>] lr : [<9ff6ef6c>]
sp : 9fefaaf0 ip : 9fefe8ec fp : 00000000
r10: 9ffa6544 r9 : 9ffa5e5c r8 : 9fefaf30
r7 : 0f800000 r6 : 9ffa6544 r5 : 9ffa65b0 r4 : 9ffa65b4
r3 : 00000049 r2 : 00000010 r1 : 00000000 r0 : 0f800000
Flags: nZCv IRQs off FIQs off Mode SVC_32
Resetting CPU ...
With dcache flush being added to my uenvcmd: complete boot
I think something of the form was highlighted here:

Not sure if there was any conclusion to the effect.
A quick tag bisect attempt was'nt too useful either.
