New description:
Hello,
could you please add support for the NB6V ? It's an evolution of the NB6
with a BCM63268 chipset, with what I think is a new CFE image format never
seen before.
I'm able to boot the latest OpenWRT via TFTP with the BCM63XX target,
generic subtarget (SMP errors out at compile time) and SFR Neufbox6
profile by modifying the "expected_cpu_id" of "board_nb6" to "0x63268" in
"board_bcm963xx.c" (otherwise it panics because the CPUID isn't correct)
and building an ELF uncompressed image, here's the boot log including the
command I use to manually load the image in RAM instead of flashing it
(disregard the modified CFE parameters, I had to change its IP and default
boot file) :

There is no more output after that and no response on the network either
(no ping, nothing); it's my first time using OpenWRT so I'm not sure if
this is the correct behavior, I guess it may have something to do with the
fact that I'm loading it from RAM and the /dev/mtd* still contains the
original SFR firmware, so OpenWRT doesn't find any of its files.
However, when I make a squashfs image for flashing the CFE doesn't like it
very much, see below when I attempt to flash it :
{{{

No more output after that.
Compare with what happens when flashing the official SFR firmware -

As you can see, it looks like the image tag/WFI tag generated by OpenWRT
isn't valid (the bootloader sees all its values as zeros) whereas the
official firmware's tag is read fine.
There are tutorials about extracting the rootfs of the official firmware
and then repacking it (I've done it and it works), it uses the "wfi-tag-
extract" utility -
http://svn.gna.org/svn/openbox4/trunk/firmware_3.x/tools/nb6v-wfi-tag-
extract/ - and the "wfi-tag-mk" utility -
http://svn.gna.org/svn/openbox4/trunk/firmware_3.x/tools/nb6v-wfi-tag-mk/
- to strip the WFI tag from the image (so that it can be extracted as a
normal jffs2) and the second utility is used to put back the stripped tag
once the new jffs2 has been made.
None of these utilities work on the images generated by OpenWRT, most
likely because the format has changed, also the "analyzetag" program
mentioned here : http://wiki.openwrt.org/_media/doc/techref/analyzetag.c
works fine with the OpenWRT generated image :

If someone could take a look at the two wfi-tag utilities and reverse-
engineer the new tag format it would be perfect; I have two of these boxes
so feel free to send me image files if you want to test stuff.
Thanks. :)

Comment:
If the new NB6 uses a different chip then this is effectively a new
device.
Please see http://wiki.openwrt.org/doc/devel/add.new.device and
SubmittingPatches on how to submit patches adding new device support.
