Re: USB Host controller for MPC8548e board

[Michael Kelly <mike@cogcomp.com>]

The reason I asked here is that they are in the kernel and seem to be 
as well supported.  I was
just more concerned if there were any PowerPC specific issues.  We 
are likely going ahead
with the NEC (since that is what was used on the G5 MAC's, I think), 
and we'll find out just how
well they work!  That's what prototypes are for.

Thanks,
Michael
