Try 'make barebox.S' and have a look at the resulting barebox.S file.
Everything including

reset
__mmu_cache_flush
imx_nand_load_image

must fit into the first 2k of memory. We currently do not catch this
(though we could using a seperate linker section for this). If your
lowlevel init code is too big then you can easily exceed this
limitation.
