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
