In u-boot I have an env var "usbethaddr" which contains what seems to be the right address (it's an RPi foundation oui). But still when booting via ubldr it generates a random address every time, apparently because smsc_fdt_find_mac() always returns zeroes (I added a printf to the smsc driver). If I hard-code the right mac address in the smsc driver I get all the way to multiuser mode. Also, when ubldr launches it immediately begins to load the kernel from sdcard before I can stop it. I have to wait for that to finish and then do "unload" then load the kernel from net0:. Can I create a file that contains different defaults or something? The amount of ram reported by kernel startup is only 128mb. u-boot says 384mb, that's not right either.
