On Marvell hardware, you can send a different U-Boot using the serial
port, even if the on-flash U-Boot is broken. Have a look at
tools/kwboot.c in the mainline U-Boot sources. It uses the serial port
to send using the Xmodem protocol, a new U-Boot payload to the Kirkwood
SoC.

Best regards,

Thomas
