I have seen the issue arise, and looked it up with the help of Jeroen
Hofstee (Cc:). It is somehow related to the fact that on ARM, U-Boot
(especially the DM) relies on ARM ELF relocation records all being of
the R_ARM_RELATIVE type, while for -O{0,1,2} the compiler generates
(some) MOVW-related relocation record types.
I have local branches related to this. I need to go through them and
will post them but not for 2013.07 as these are not fixes, and there
is no bug per se since U-Boot is supposed to build with -Os, not
-O{0,1,2}.
