^ I wonder why are you overriding CONFIG_ZBOOT_LOAD_ADDRESS here, automatic
calculation should work well.
Also I think by adding board-eyeq5.config you are hijacking CONFIG_PHYSICAL_START
for `make 32r2el_defconfig` without BOARDS option as well.
Probably we should implement something to backlist this board from generic
config.
Thanks
