Well, I downloaded the entire kernel via tftp, so the controller was probably
configured correctly. Probably, u-boot resets it after transfer (have not checked
this yet).
The idea of bd_t support looks promising anyway, especially if we'll continue our
expansion in the embedded world (almost all powerpc and arm embedded boards are
moving toward using u-boot exclusively). This way we'll get a good cooperation
with another projects. I'll look into this after I get ate0 and usb working.
BTW, what is the status of usb for now? Should it work? I'm receiving
a 'device problem (IOERROR), disabling port 1' message if device attached.
Is it known problem, or something is misconfigured in my board?
Thanks for information!
