Multiple MPC8xx SCC ethernets

Multiple MPC8xx SCC ethernets

[Martin, Tim]

I'm looking for patches to allow multiple SCC based ethernets on MPC8xx
based boards.  The 2.4 kernel releases only allow selection of either SCC1,
SCC2, or SCC3, but not all three at the same time.

Twice in the last few months, there's been a thread discussing this but I've
never seen any code posted to the list.  Could someone send me / point me to
any available patches?

Thanks,
Tim

Horiuchi Satoshi had sent me his patch before. After I patched
to 2.4.12, then to 2.4.13, it worked smoothly. There are three
main modifications. One is in drivers/net/setup.c, adding the
second SCC enet setup entry. The second is in arch/ppc/8xx_io/
Config.in, adding the config option. The last is in enet.c,
adding the second SCC init code, set_muticast_list and interupt
handler, which looks like the first SCC code very much except the
SCC numbers.

A more elegant scheme is needed to figure out, I think.
