This adds some code based on code from the Broadcom GPL tar to fix the
reboot problems on BCM4705/BCM4785. I tried rebooting my device for ~10
times and have never seen a problem. This reverts the changes in the
previous commit and adds the real fix as suggested by Rafał.
Setting bit 22 in Reg 22, sel 4 puts the BIU (Bus Interface Unit) into
async mode.

A reboot is issued by setting the watchdog timer to a low value, when
the value is decreased from 1 to 0 by the hardware the system will
reboot. Setting this value to 1 does not work every time, it is a
little bit more reliable when setting it to 3. This timer runs with
some MHz or KHz so nobody will notice the increased waiting.

When the Ethernet controller is powered down and someone wants to
access the mdio bus like the witch driver (b53) the system crashed if
PCI_D3hot was set before. This patch deactivates this power sawing mode
when a switch driver is in use.

Now the mac address is increased by two for the first fallback mac
address. It could be that the address increased should be used for the
wan port.

The address prefix 00:90:4C is used by Broadcom in their initial
configuration. When a mac address with the prefix 00:90:4C is used
all devices from the same series are sharing the same mac address.
To prevent mac address collisions we replace them with a mac address
based on the base address.

We did not start the PHY when an external phy was in use. Without this
patch the driver uses half duplex mode and the switch uses full duplex
mode, which causes problems.
Thank you fback for spotting this problem.

bcm47xx misses cpu overwrites for the features of the CPUs used in
these SoCs.
Instead of manually checking, it is now known at compile time for some
options and the compiler is able to remove the checks and optimize the
code.

brcm47xx: use old partition names again for kernel 3.8
This fixes sysupgrade. The partition names are used all over the Internet in various howtos.
Thank you russell for spotting this problem.
I propose to revert this change and make sysupgrade use "firmware"
instead. This makes brcm47xx compatible with widely used ar71xx and
after all "firmware" sounds like a much better name for... the firmware.
This change doesn't affect "sysupgrade" usage, because it never takes a
partition name as a parameter. This change only affects users using mtd
tool directly. Hopefully there are not many howtos using "mtd" command.

Some devices are using tty1 as the default console, also swap the early
boot console in such case. This is needed for the WGT634U.

boardnum is unstable, so allow using NULL to make it unchecked.
A method for differentiating F7D3301 from F7D3302 using nvram is
unknown at this point. Reading the first 32bits of magic from the
"linux" mtd partition would do the trick, but these 2 are similar
enough that we don't need separate led/button definitions. Not knowing
which one you have is only a usability issue for upgrading the device:
they expect different magic numbers for their trx images.
