I want to use FEC(100M) and SCC1(10M) interface,but they can
not work together.
     When I use ppcboot with CONFIG_SCC1_ENET defined , boot
linux ,then SCC1 is ok,when I ping FEC (I config it ip
address is 192.168.2.221) it displayed messaged "time out".
     When I use ppcboot with CONFIG_FEC_ENET  defined,  boot
linux ,then FEC is ok, when I
ping SCC( I config it ip address is 192.168.1.198) it
displayed messaged also "time out".

For FADS PPCBoot sets up both BCSR1 and BCSR4 in cpu/mpc8xx/scc.c.
In Linux 2.4.18 only BCSR1 is configured in arch/ppc/8xx_io/enet.c
Maybe configuring BCSR4 in enet.c would help.
