[meta-freescale] u-boot fails building with gk802 (hdmi dongle) as MACHINE, hard-float issue?

[Christian Betz]

I found the answer and I was able to build u-boot (and
core-image-base) successfully after modifying
arch/arm/cpu/armv7/config.mk as described at the link below [1]

A patch will be forthcoming in the early AM.

>From my build configuration which is printed when I run bitbake, I
have the following variables:

TUNE_FEATURES     = "armv7a vfp neon callconvention-hard cortexa9"
TARGET_FPU        = "vfp-neon"

Should I be checking for callconvention-hard in TUNE_FEATURES? Or is
it OK if I just check DEFAULTTUNE_mx6 directly? (since this is a
u-boot for a specific machine)
