[PATCH 3/3] [POWERPC] 86xx: mpc8610_hpcd: use ULI526X driver for on-board ethernet

[Anton Vorontsov]

As of current mainline tree, TULIP driver is unusable on MPC8610HPCD
boards. There is a patch[1] floating around (and also included in the
BSP), which tries to heal the situation, though the ethernet is still
unusable. Practically it takes ages to mount NFS filesystem:

VFS: Mounted root (nfs filesystem).
Freeing unused kernel memory: 180k init
nfs: server 10.0.0.2 not responding, still trying
nfs: server 10.0.0.2 OK
nfs: server 10.0.0.2 not responding, still trying
nfs: server 10.0.0.2 not responding, still trying
nfs: server 10.0.0.2 not responding, still trying
nfs: server 10.0.0.2 not responding, still trying
nfs: server 10.0.0.2 OK
nfs: server 10.0.0.2 not responding, still trying

So, instead of trying to add uli526x functionality into TULIP driver
(which is already bloated enough), I fixed existing ULI526X driver
and now it works perfectly well here.

I'm assuming patches that fix the uli526x driver have been accepted by  
jeff.

After applying this patch and Anton's two ULI driver patches, the ULI drivers
works great on an 8610HPCD.
