From b7edc84a9619eb2c8bfb5265d4079da9c70ad270 Mon Sep 17 00:00:00 2001 From: Rod Whitby Date: Sat, 2 Feb 2008 00:04:05 +0100 Subject: [PATCH] [ARM] 4806/1: ixp4xx: Ethernet support for the nslu2 and nas100d boards Enables the new ixp4xx qmgr and npe drivers in ixp4xx_defconfig. Sets up the corresponding platform data for the nslu2 and nas100d boards, and reads the ethernet MAC address from the internal flash. Tested on both little-endian and big-endian kernels.
