Adds support for loading U-Boot from UART using YMODEM protocol. If YMODEM support is enabled in SPL and the romcode indicates that SPL loaded via UART then SPL will wait for start of a YMODEM transfer via the console port.
:-) I like this feature!
I tried something similar a few month ago for the da850evm and my own board, it worked but I never had time to finished it and submit it, it was just a hack.
For my tests I used the UART loader utility from TI to load the SPL and then minicom for loading u-boot. Do you have an automated solution for this? Would be nice to have something like this in tools/.
IIRC the da850evm ROM needs a special tool to load via UART. omap4/5/am33xx ROM does XMODEM for real so 'sx' works fine.

Could this be somewhere where it's accessible for other SoC families like davinci? E.g. We have nand_spl_load.c in drivers/mtd/nand and something similar for SPI flash.
In theory, sure, just need a location to place it at.
