Can we use all SCCs with MPC860

Can we use all SCCs with MPC860

[LEROY Christophe]

Hello,

I have a board (home made) with a MPC862 running Montavista Linux 2.1
(kernel 2.4.17).
I'd like to use the four SCCs as serial ports, but it seems that only
SCC2 and SCC3 can be configured as serial ports.
Does someone have any idea on how to configure SCC1 and SCC4 as serial
ports also with that kernel ?

Thanks
C. Leroy

It's not difficult to extend the 8xx  UART  driver  to  support  both
SMC's  and  all  4 SCC's. This has been done before; see for examplee
the kernel source in our CVS server (module linux-2.4). This has been
tested and actually used (with hardware flowcontrol) on a  couple  of
boards.

that kernel = MV Linux 2.1? Seems you should ask MV....
