Is there a good platform/documents to look at for doing a board port from arch/ppc to arch/powerpc? I'm porting a 8266/8280 based board with PCI and 2 FCC ethernets connected phy-less to a switch.

Look at head-of-tree for 82xx stuff (lots of changes since 2.6.23)... any of the 82xx boards in arch/powerpc should be good to look at. The fs_enet driver doesn't currently support phy-less directly, but you may be able to do something with the fixed phy driver. -Scott

How is PHY less support supposed to be impl.? I would like to do the same for ucc_geth. I once sent a patch that made the PHY optional, but it never made into the driver. Jocke

Basically, the driver needs to assume the link is up if there's no phy-handle in the device tree, rather than error out. -Scott

Right, that was what I did, but I think Leo didn't want it at the time. Leo? Jocke
