[U-Boot] Automatic download and flash programming with UART boot

Hello,

The documentation [1] for the AM335x defines a manual process for UART booting as including the steps...

When 'CCCC' appear select XMODEM -> Send "u-boot-spl.bin", and then...

When 'CCCC' appear select YMODEM -> Send "u-boot.img"

Is there a pre-existing tool or script around that will automate this process which can then be used with a U-Boot debrick script to program the on-board flash devices?

Thanks,

Andy.
