Recently, I'm porting Linux 2.6.32.6 to our customized MPC8247 based
board. Everything is fine out except my ethernets. I uses
cpm2-scc-enet and cpm2-fcc-enet drivers.
My ethernet works fine in U-Boot with the same setting, and our
previous Linux 2.6.22 is also working, so there should be nothing
wrong with the hardware.
The boot log of the MII part is:
CPM2 Bitbanged MII: probed
mdio_bus f0010d00: error probing PHY at address 0
mdio_bus f0010d00: error probing PHY at address 1
Are 0 and 1 the addresses you're expecting the PHYs to be at?
If that's not it, I'd try to examine the specific register accesses that
2.6.22 is doing and see what's different.
