At some point, EHCI seems to have started working on sh64. It appears
to be fine on 2.6.7 and 2.6.8-rc1. I don't know whether there was a
change in the driver between 2.6.6 and 2.6.7 that would explain this, or
whether it could have been some architecture fixes that happened in the
same kind of timeframe. (We started off porting against 2.6.6 and
rebaselined to 2.6.7 after that came out.)
Anyway, thanks for your help.
Cheers
Richard
