This changes the name of the output device from "lcd" to "vidconsole".
Anyone who doesn't reset their environment to default when switching to
this new U-Boot will lose their display output because of this. Is there
any way to maintain compatibility?
Aside from that, I don't see any issues on Springbank (Seaboard),
