Hi all,

I have a custom board with an MPC8358 (our board is based
off of the MPC8360E-MDS development board) that has its eth's
directly connected (GMII) to a Broadcom network switch
part on the same board, with no PHYs between them.
We've have been using a kernel (from TimeSys) up
until now, and I hacked in some crude support for no-phy
configs forced to 100Mbit and 1Gbit speeds.   Now I'm
moving to 2.6.22 (with 8360 the patches from,
and I'm trying to understand how I should do this with
device trees, the new PHY infrastructure, etc.   Has anyone
else needed this support?   Does anyone have any suggestions
as to how to tackle it?
