bcm53xx: update bcma device tree intergeneration and fix nvram parsing
This fixes lots of sparse and checkpatch errors and extends the documentation. This also fixes a problem in the nvram parser, it now detects the correct nvram on my Netgear R6250. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> SVN-Revision: 42272

+ space
-Moving mach-bcm47xx/bcm47xx_nvram.h makes it possible to reuse this
-header on the arm bcm47xx (BCM5301X) devices. This way a driver gets
-the correct functions to access the nvram depending on the SoC it boots
-for.
+Moving mach-bcm47xx/bcm47xx_nvram.h to include/linux/bcm47xx_nvram.h
+makes it possible to reuse this header on the ARM based bcm47xx/bcm53xx
+SoCs (e.g. BCM5301X devices). Broadcom uses ARM CPUs in their new SoC
+form the bcm47xx and bcm53xx line, but many other things like nvram
+stayed the same.
+
+This is a preparation for adding a new nvram driver, which can be used
+by the ARM SoC and the MIPS SoC code. The device drivers accessing
+nvram do not have to care about ARM or MIPS SoC version.

-+ This adds support for the brcm53xx sprom driver.
++ This driver parses the sprom from a given nvram which is found on
++ Broadcom bcm47xx and bcm53xx SoCs.
++
++ The sprom contains board configuration data like the
++ calibration data fro the wifi chips, the mac addresses used
++ by the board and many other board configuration data. This
++ driver will provide the sprom to bcma.

++Broadcom AIX bcma bus driver
++
++
++Required properties:
++
++- compatible : brcm,bus-aix
++
++- reg : iomem address range of chipcommon core
++
++Optional properties:
++
++- sprom: reference to a sprom driver. This is needed for sprom less devices.
++ Use bcm47xx_sprom for example.
++
++
++The cores on the AIX bus are auto detected by bcma. Detection of the
++IRQ number is not supported on BCM47xx/BCM53xx ARM SoCs, so it is
++possible to provide the IRQ number over device tree. The IRQ number and
++the device tree child entry will be added to the core with the matching
++reg address.
++
++Example:
++
++ aix@18000000 {
++ compatible = "brcm,bus-aix";
++ reg = <0x18000000 0x1000>;
++ ranges = <0x00000000 0x18000000 0x00100000>;
++ #address-cells = <1>;
++ #size-cells = <1>;
++ sprom = <&sprom0>;
++
++ gmac@0 {
++ reg = <0x18024000 0x1000>;
++ interrupts = <GIC_SPI 147 IRQ_TYPE_LEVEL_HIGH>;
++ };
++
++ gmac@1 {
++ reg = <0x18025000 0x1000>;
++ interrupts = <GIC_SPI 148 IRQ_TYPE_LEVEL_HIGH>;
++ };
++
++ pcie@0 {
++ reg = <0x18012000 0x1000>;
++ interrupts = <GIC_SPI 131 IRQ_TYPE_LEVEL_HIGH>;

+Subject: [PATCH 13/17] pcie2-bcma: add new PCIe2 driver for bcma
This driver supports the PCIe controller found on the BCM4708 and
similar SoCs. The controller itself is automatically detected by bcma.
