Subject: [PATCH v2 00/12] Device Tree support for the at91sam9261ek

This patch set aims at bringing a basic device tree support for the sam9261.
It's mostly based on the sam9263 stuff.
It introduces a new driver for the smc/ebi bus. It's used to configure the EBI
from the DT. I haven't documented its DT bindings yet. Timings can be provided
as raw values or nanoseconds.

Change since V1:
* changed the DT representation to use address translation and separate the
  timings' configuration from the device properties by adding a "simple-bus"
  inetrmediate node.
* moved the smc driver from drivers/bus to drivers/memmory
* smc driver now accepts timings in nanoseconds as well as raw register values
* smc driver can clip the timings if they're out of bound and dump them to the
  console
* DM9000 timings are now described in nanosecs (for the virtue of example)

supported features:
* dbgu
* nand
* lcd
* ethernet
* leds
