Re: I2c

[Erik Anggard <erik.anggard%packetfront.com@localhost>]

I've written a device driver for the I2C-interface built into mpc824x, I 
belive it's equivalent to that of the mpc107. If you like I can send you 
the code (I'll have to check with our management first since it is part 
of a company product), but I'm sure your code is probably better that 
the stuff I wrote anyway (I haven't written any autoconfiguration for 
starters).  I'd be very pleased  if a driver for this would be added to 
the netbsd-source (that way I wouldn't have to continue maintaining my 
own driver :).

Is it possible to get a look at your code?

Best regards,
Erik Anggard
