[PATCH] Support for NEC VR4133 in 2.6

[Manish Lachwani <mlachwani@prometheus.mvista.com>]

[-- Attachment #1: Type: text/plain, Size: 310 bytes --]

Hi Ralf

Attached patch implements support for NEC VR4133 and NEC Rockhopper in
2.6. Currently there is no ethernet driver for the ports on the CMB-VR4133.

The board has been booted with the Onboard PcNet32 network interface and with
an Intel EEPRO100 PCI NIC card.

Please review ...

Thanks
Manish Lachwani
