A binary built with CONFIG_KALLSYMS is >256k and without CONFIG_KALLSYMS
it's smaller than 256k. Looking at the karo i.MX51 flash_header.c it
seems it does it right:

unsigned long __image_len_section barebox_len = DCD_BAREBOX_SIZE;

Nevertheless 256k is a typical maximum bootloader size which is assumed
in some places, I would start looking there.
