Subject: 83xx, ucc_geth, kernel 2.6.23, IP-Config: No network devices
Date: Mon, 7 Jan 2008 02:54:53 -0800	[thread overview]
Message-ID: <000001c8511b$bc0c03d0$6405a8c0@absolut> (raw)

Ok, I am still stuck on this. 
Why isn't probe being called on any of the Freescale network device drivers?

I can see the Generic MII PHY Driver being registered.
The UCC_GETH and UCC_GETH_MDIO both being registered. 

An for fun, I even modified the Marvell PHY driver devices ID's to correctly
identify a National part that I am using, and I see this registering.

I would appear all the appropriate entries are in the .dts file
for each the different parts (mdio, ucc_geth, ucc_geth_mdio, phy0).

And yet still no probe functions get called for any of those drivers?

I need this to NFS boot, into the ELDK 4.1 file system.

Does anyone have an example of the 2.6.23 kernel working DTS files for a
Freescale 8360 that they are using NFS Booting for? Has anyone proofed this
out, or is everyone else using this as a module or driver that doesn't kick
until after the root file system is loaded?  

Alternatively is there something specific perhaps U-boot is populating in
the OF structure that is preventing my Ethernet phy from being recognized in
the linux kernel? Why are none of the probe functions being called?
