I've seen the application notes on manual configuration. Specifically I have a Beagleboard variant that I'm using an ADIN1300 and ADIN1200 on. A U-boot initialization will be a lot cleaner.
To ask this another way, is the ADIN1300/ADIN1200 Linux driver
supported by U-boot to enable booting Linux over Ethernet? If not, is that because this is considered a No-OS driver?
