Hauke Mehrtens cdc7ea3337 bcm53xx: add support for the PCIe controller 
This patch adds support for the PCIe controller
In addition to the PCIe controller a sprom is now provided by a device
tree driver to bcma from some nvram.

Subject: [PATCH 04/15] bcm53xx-sprom: add sprom driver
This driver needs an nvram driver and fetches the sprom values from the
sprom and provides it to any other driver. The calibration data for the
wifi chip the mac address and some more board description data is
stores in the sprom.
