RE: [ECOS] MPC860 - devs/serial/quicc

["Philip Soeberg" <ecos at soeberg dot net>]

Now that the QUICC serial issue is up...

Are there any plans on extending the routing of SCC3 to CPU types other than
MPC850/MPC852T?

Sadly, I'm forced to use SCC3 on an MPC823 CPU, why I have been forced to
implement various hacks to the QUICC module... As I don't know the reason
why CPU's other than the ones mentioned isn't supported, I have not created
a generic patch for the CVS...

All combinations of SMC1/SMC2/SCC1/SCC2/SCC3/SCC4 should be supported
for both diagnostic I/O and high-level (interrupt driven) drivers.
Get the latest CVS - not all of this was in v2.0

Look at the A&M Viper for examples of how to configure using both
SMC1 & SCC1, including console (RedBoot) and /dev/serX I/O
