Not sure, but it can certainly serve as additional documentation and
prior art. Also, it would be interesting to know what problems they ran
into and what they did about them.
Getting it to boot *something* shouldn't be hard - our build system can
spit out uboot images when asked to. That's what I did with CI20, I'm
not even sure we support any other uboot-on-MIPS configuration.
Does uboot use a serial port as console? It's probably some sort of
16550 workalike. If uboot used it then we don't even need to configure
it, just poke data into the send register.
Also, as Frank said, I'd try an e500 kernel first, I wouldn't be overly
surprised if there's some sort of backwards compatibility in newer

have fun
