Broadcom ARM home routers store SPROM content in NVRAM just like MIPS
ones. To share SPROM code we need to move it out of arch/mips/ to some
common place. We already have bcm47xx_nvram in firmware path and SPROM
should fit there as well.
This driver is responsible for parsing SoC configuration data into a
struct shared between ssb and bcma buses.
This was tested with BCM4706 & BCM5357C0 (BCM47XX) and BCM4708A0
(ARCH_BCM_5301X).

This old wgt634u.c was trying to implement a bit ugly support for
Netgear WGT634U. It provided info about LED, flash mapping & layout and
was trying to handle reset button.
This is not needed anymore as we have replacement for all this stuff.

So far this adds support for one Netgear model only, but it's designed
and ready to add many more device. We could hopefully import database
from OpenWrt.
Support for SSB is currently disabled, because SSB doesn't implement IRQ
domain yet.

So far this is mostly just a proof of concept, database consists of a
single device. Creating a nice iterateable array wasn't an option
because devices have different amount of LEDs. And we don't want to
waste memory just because of support for a device with dozens on LEDs.

Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.

Move the sprom parsing from nvram into sprom.c. There are all values
needed for sprom version 1 to 9 read from nvram and there are more
sanity checks added. This is based on the sprom parsing in the open
source part of the Broadcom SDK.

When trying to netboot a Linksys WRT54GS WLAN router, the bootup fails,
because of following error message:
...
[ 0.424000] b44: b44.c:v2.0
[ 0.424000] b44: Invalid MAC address found in EEPROM
[ 0.432000] b44 ssb0:1: Problem fetching invariants of chip,aborting
[ 0.436000] b44: probe of ssb0:1 failed with error -22
...
The router uses a CFE bootloader, but most of the needed environment
variables for network card initialization, are not available from CFE
via printenv and even though not via cfe_getenv().
The required environment variables are saved in a special partition
in flash memory. The attached patch implement nvram_getenv and enables
bootup via NFS root on my router.
Most of the patch is extracted from the OpenWrt subversion repository and
stripped down and cleaned up to just fix this issue.
[Ralf: sorted out header file inclusions. Lots of unneded headers and such
that should have been included.]

Add LED support to the WGT634U machine. It uses the new gpio-led
driver and a platform driver for the pin definitions.
