I tried, but I'm having a really hard time figuring out how the fpu
selection works for other boards or finding any code related to
hard-float that I can blame. since config.mk has the -msoft-float in
u-boot master and there no patches I can find that would change it.

in other words, mainline u-boot appears to still have the following
line in arch/arm/cpu/armv7/config.mk:

 PLATFORM_RELFLAGS += -fno-common -ffixed-r8 -msoft-float

and I can't find any recipes/patches that are changing it. so i'm
scratching my head wondering how the heck u-boot builds with hard
float for all the other boards.

I'm hoping someone else has some pointers. I would like to do this the
"right" way but i'm currently lost. Or maybe i've just been awake too
long ;)
