What I've got so far. Currently it does not get any further than the following:
U-Boot SPL board init spl_early_init SPL malloc() before relocation used 0x23c8 bytes (8 KB)
SPL: board_init_r()
spl_init SPL: Unsupported Boot Device! SPL: failed to boot from all boot devices ERROR ### Please RESET the board ###
Posting to the lists so someone could perhaps assist
