From 0510c8a014432b45f09509d1fb450922ec96b40d Mon Sep 17 00:00:00 2001 From: Valentin Longchamp Date: Tue, 4 Sep 2012 11:55:02 +0200 Subject: ARM: initial DTS support for km_kirkwood This is a first attempt to support the km_kirkwood reference design with a device tree. This km_kirkwood design is present in many Keymile products. It is based on the Marvell Bobcat SOC which integrates a Kirkwood CPU next to a big L2 Ethernet Switch. The Kirkwood in the SOC is very similar to the "normal" one, but there are a few differences. This initial support is minimal: the kernel can boot with network (ge0), serial port and NAND functional.
