For my boards, I had to modify the -u-boot.dtsi files [1] because the gpmc driver didn't have a driver, so any sub-nodes disappeared leaving the Ethernet unavailable. With the fix Ethernet works.

Here beagle ethernet is via an onboard USB ethernet device. My networking tests are as stable as ever (I can't get NFS to work on any of them, but TFTP and EFI network are fine).

I tested this patch on my BeagleBoard Rev. C4 and BeagleBoard xM.

Tested-by: Derald D. Woods woods.technical@gmail.com

NOTE:

I did have to perform a 'make menuconfig' and set DM_ETH and DM_USB manually though. It may be something cached in my build environment. I mention this because I did perform an additional operation before build.

After first use of defconfig: ---8<---------------------------------------------------

That's just very odd. If you start from a clean tree and apply the patch is it reproducible? Thanks!
