bcm53xx: update bcma device tree intergeneration and fix nvram parsing

Browse Source 
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.

Subject: [PATCH 02/15] bcm47xx: move the nvram header file into common space
Subject: [PATCH 01/17] MIPS: BCM47XX: move the nvram header file into common
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 a new driver which searches at a given memory range for a
nvram like it is used on the bcm47xx and bcm53xx SoCs with ARM and MIPS
CPUs. This driver provides acces to this nvram to other device in the
device tree. You have to specify the memory ranges where the content of

mac address and also for configuration values in the vendor firmware.
mac addresses, the switch configuration and the calibration data for
the wifi devices.
This was copied from arch/mips/bcm47xx/nvram.c and modified to interact
with device tree. My plan is to make the MIPS bcm47xx also use this new
driver some time later.

wifi chip the mac address and some more board description data is

This driver is used by the bcm53xx ARM SoC code.Now it is possible to
give the address of the chipcommon core in device tree.
This driver is used by the bcm53xx ARM SoC code. Now it is possible to
give the address of the chipcommon core in device tree and bcma will
search for all the other cores.

+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>;
+ };

If bcma was registered with device tree it will search for some nodes
with the irq number and add it to the core configuration.
It is not possible to auto detect the irq numbers used by the cores on
an arm SoC. If bcma was registered with device tree it will search for
some device tree nodes with the irq number and add it to the core
configuration.
