there could be more to it, since the distro uses thumb2 ISA by
default, I am not sure
if u-boot overrides that and builds using arm mode ISA always but
something to consider, I saw several reports about u-boot overflowing
sram sections and most of
the solutions were "oh it works for me" or at the best your toolchain
is different then mine. here is mine use it and move on.
