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

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.

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.

This patch adds support for Huawei E970 wireless gateway devices.
It has been tested on an E970 labelled as T-Mobile web'n'walk Box IV.
E960/B970 should work too, from what I know it's basically the same hardware.
The device has a Broadcom BCM5354 SoC and a built-in 3G USB modem.
It uses a hardware watchdog which needs GPIO-7 to be toggled at least
every 1-2 seconds. This patch uses gpio_wdt module (see my previous
patch today) to take care of this.
Tested and works: 3G wan, wlan+LED, VLAN config, failsafe using reset
button, image to be used for upgrade from OEM firmware's web interface
Link to the wiki page I've created: <http://wiki.openwrt.org/toh/huawei/e970>
Issue:
* lzma-loader crashes, so gzipped kernel is used. Presumably due to watchdog
reset during kernel decompress.

This is important patch for new devices that support unaligned
addressing. That devices suffer from the backward-compatibility bug in
DMA engine. In theory we should be able to use old mechanism, but in
practice DMA address seems to be randomly copied into status register
when hardware reaches end of a ring. This breaks reading slot number
from status register and we can't use DMA anymore.

Most of the bcm47xx devices use TRX format for storing kernel and some
partition like Squashfs or JFFS2. This is pretty flexible solution, CFE
(the bootloader) just writes (and later boots) TRX at some hardcoded
place and paritions can vary in the size.
However some devices don't use TRX format. Very recently we have
discovered ZTE H218N that has kernel and rootfs partitions at some
"random" places.
This patch allows Linux find a rootfs partition after installing custom
image with a CFE bootloader.
