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
