That's strange. I can confirm what Ahmad said: starting from imx_v7_defconfig and deselecting MACH_CCMX51 still leaves RELOCATABLE enabled here. I have no idea why this is different for you. Anyway, on i.MX a barebox binary with RELOCATABLE disabled only works in very special cases and requires setting TEXT_BASE to a suitable value, one that works on all boards selected. It would be nice to hide RELOCATABLE from the user in most cases.
