[U-Boot-Users] BUBINGA405EP Platform

It's me, again...

I have a bubinga 405 reference platform, and it behaves very well with the
PROM from IBM, but I am unable to get u-boot running on it.

It takes an exception to either 0700 or 0200 after executing very early in
the bootloader.  The ppc405ep_init function just starts, and actually causes
a machine exception on the 5th assy line... andi. R6,r5,8  which looks
completely valid to me...  At this point in the game, icache and dcache have
been invalidated, and not much else has been done.

If someone has worked with the RISCwatch on this board, would you please
send me your startup.cmd file?

Any ideas would be welcome...
