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.

The BCM4706 has a problem with the CPU wait instruction. When r4k_wait
or r4k_wait_irqoff is used will just hang and not return from a
msleep(). Removing the cpu_wait functionality is a workaround for this
problem. The BCM4716 does not have this problem.
The BCM4706 SoC uses a MIPS 74K V4.9 CPU.

The BCM47xx SoCs have a 8250 serial compatible console at address
0x18000300 and an other at 0x18000400. On most devices 0x18000300 is
wired to some pins on the board, we should use that.
This is the smae for the AI (bcma) and the SB (ssb) bus, this is some
offset on the chip common core.

The ADM6996L switch and some Broadcom switches with two MII interfaces
like the BCM5325F connected to two MACs on the SoC, used on some
routers do not return a valid value when reading the PHY id register
and Linux thinks there is no PHY at all, but that is wrong.
This patch registers a fixed phy in the arch code and then searches it
when there is no other phy in the Ethernet driver code.

Some BCM5354 SoCs are running at 200MHz, but it is not possible to read
the clock from a register like it is done on some other SoC in ssb and
bcma. These devices should have a clkfreq nvram configuration value set
to 200, read it and set the clock to the correct value.

Also resolves a logical merge conflict in drivers/net/ethernet/broadcom/-
bgmac.c due to change of an API.
An SoC normally do not define path variables for board_rev and
board_type and the Broadcom SDK also uses the nvram values without a
prefix in such cases. Do the same to fill these sprom attributes from
nvram and do not leave them empty, because brcmsmac do not like this.

The old code just worked for nvram with a size of 0x8000 bytes. This
patch adds support for reading nvram from partitions of 0xF000 and
0x10000 bytes.
There is just 32KB space for the nvram, but most devices do not use the
full size and this code reads the first 32KB in that case and prints a
warning.

Pull MIPS updates from Ralf Baechle:
"The MIPS bits for 3.8. This also includes a bunch fixes that were
sitting in the linux-mips.org git tree for a long time. This pull
request contains updates to several OCTEON drivers and the board
support code for BCM47XX, BCM63XX, XLP, XLR, XLS, lantiq, Loongson1B,
updates to the SSB bus support, MIPS kexec code and adds support for
kdump.
When pulling this, there are two expected merge conflicts in
include/linux/bcma/bcma_driver_chipcommon.h which are trivial to
resolve, just remove the conflict markers and keep both alternatives."

There are bcma based devices like the Linksys E2000 out there, which do
have one ieee80211 core, but no PCIe core and they are using no
prefixes for the sprom. In addition some values like boardtype are
stored without a prefix for the main SoC chip also when they have an
additional PCIe wifi chip with an own boardtype var on some devices.
The Ethernet addresses are now also read out correctly without a prefix
so calling bcm47xx_fill_sprom_ethernet is not needed any more.

The memory size is detected by finding a place where it repeats in
memory. Currently we are just checking when the function prom_init is
seen again, but it is better to check for a bigger part of the memory
to decrease the chance of wrong results.
This should fix a problem we saw in OpenWrt, where the detected
available memory decreed on some devices when doing a soft reboot.
