There are two reasons for having this header in the common place:
1) Simplifying drivers that read NVRAM entries. We will be able to
safely call bcm47xx_nvram_* functions without #ifdef-s.
2) Getting NVRAM driver out of MIPS arch code. This is needed to support
BCM5301X arch which also requires this NVRAM driver. Patch for that
will follow once we get is reviewed.

Catalin reported that GPIOs used by bcm47xx don't match layout of his
WRT54GS V1.0 board. It seems we need to distinguish these 54G* devices.

Add a few Belkin F7Dxxxx entries, with F7D4401 sourced from online
documentation and the "F7D7302" being observed. F7D3301, F7D3302, and
F7D4302 are reasonable guesses which are unlikely to cause
mis-detection.

This adds board detection for the Siemens SE505v2 and the led gpio
configuration. This board does not have any buttons.
This is based on OpenWrt broadcom-diag and Manuel Munz's nvram dump.

The Linksys WRT54G/GS/GL family uses the same boardtype numbers, and
the same gpio configuration. The boardtype numbers are changing with
the hardware versions, but these hardware numbers are different or each
model.
Detect them all as one device, this also worked in OpenWrt.

Detect on which board this code is running based on some nvram
settings. This is needed to start board specific workarounds and
configure the leds and buttons which are on different gpios on every board.
This patches add some boards we have seen, but there are many more.
