From: Tien Fong Chee <[email protected]> Add 'scriptfile' and 'fatscript' environment variables to the SoCFPGA common config so that users can drop an optional U-Boot script (u-boot.scr) on MMC partition 0:1 and execute it without modifying the source code. This is useful for board-specific customisation such as register tweaks at boot time. The script is optional and not required for normal booting; users can invoke it manually with "run fatscript" or include it in their bootcmd as desired.
