ToT seems to be working fine for me (using different PHYs though):

you can try applying commit 71bd860cce4493c5def07804723661e75271052b
"mpc83xx: don't shift pre-shifted ACR, SPCR, SCCR bitfield masks in
cpu_init." but I don't think that's the problem, since it doesn't
affect the p2020.

Upgrade to ToT?  Start a git bisect?  on drivers/net/tsec.c?
