[U-Boot] warning: override: reassigning to symbol OF_CONTROL

Hi Simon,

I've rebased my git repo on u-boot-x86/master branch and found one warning popped up:

$ make crownbay_defconfig HOSTCC scripts/basic/fixdep HOSTCC scripts/kconfig/conf.o SHIPPED scripts/kconfig/zconf.tab.c SHIPPED scripts/kconfig/zconf.lex.c SHIPPED scripts/kconfig/zconf.hash.c HOSTCC scripts/kconfig/zconf.tab.o HOSTLD scripts/kconfig/conf arch/../configs/crownbay_defconfig:23:warning: override: reassigning to symbol OF_CONTROL

Do you know where is this coming from?

Regards, Bin
