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.

Add two helpers for generating correctly tagged images for the T-Home
Speedport W 303V Typ B as well as xor'd ones as required by CFE.

Dual image capable CFEs store an image sequence at the same place as
currently OpenWrt stores the actual rootfs length, so it will get
overwritten when flashing through such a CFE.
To prevent this from happening, move the rootfs length field to the next
four bytes, thus completely using the reserved1 field.
Since the reserved1 field is now completely in use, it does not make sense
to allow it to be set from the imagetag utility, so remove the option.

CFE does not boot images generated with these checksums because of
wrong checksum.
After flashing then with tftp to my Asus wl500-GPv1 the following messages
are show:
Null Rescue Flag.
Boot program checksum is invalid
Hello!! Enter Rescue Mode: (Check error)

* reduce image size for CRC calculation by fs_mark size
sysupgrade sometimes failed for me and I noticed that it was due
to incorrect CRC values in trx-header after performing it.
It seems that the fs_mark was completely included in the calculation
and that it was nevertheless modified by sysupgrade while appending
the jffs data.
This only occurs for the first boot after sysupgrade as the flashmap
driver recalculates the CRC to an even smaller area when it boots.

Attached patch enhances the mktplinkfw utility:
1. existing firmware files in TP-Link format can now be inspected, showing eg. the used offsets
2. optionally the kernel and rootfs parts can be extracted (saves calculations for dd)
3. when generating firmwares, kernel entry point, load address and rootfs offset can be overwritten (for experienced users)
