John Crispin 5d3f0eea1c tools/firmware-utils: Allow changing the CRC32 poly value in mkbrnimg
VGV7519 is currently the only device with brnboot support. It seems to
be happy with 0x2083b8ed as CRC32 poly. However, VGV7510KW22 fails to
validate the checksum - it requires 0x04c11db7 instead.

I have built an brnboot image manually on the command line, once with
the old code and then with the new code but passing the old CRC32
poly value. Both resulted in a brnboot image with the same sha1sum.

John Crispin cd1a204365 Support booting the Speedport W502V using BRN-BOOT.
While the disadvantage is less available flash space, it's easy and
safe to flash without opening the device.
Going back to the original firmware is also possible.

This patch add two firmware utilities, mkbrncmdline and mkbrnboot.

mkbrncmdline patches the uncompressed kernel so the registeres a0 to
a3 are initialized and the memory size is passed in.

mkbrnboot takes the lzma compressed kernel and squashfs images and
creates a firmware image that can be flashed using the BRN-BOOT
recovery kernel, which is booted by holding both buttons when
powering up the device and will listen on http://192.168.2.1.

The firmware file from bin/lantiq/ to use is
openwrt-lantiq-danube-ARV4525PW-BRNDTW502-brnImage

The BRN-BOOT recovery kernel does size-check the image, so if it's
too big to fit into flash it will complain accordingly.

A second patch is needed to make the wired network interface work
since there is no u-boot to pre-initialise it.
