I wanted to generate chk image for WNDR4500. For that I need to hack
target/linux/brcm47xx/image/Makefile

For chk files mkchkimg is used with 2 parameters I've to find out:
board_id and region. My guess is I have to extract that parameters
from stock (original) firmware to understand what my router accepts.
Is that right?

For that purpose I've downloaded WNDR4500-V1.0.0.103_1.0.21.chk and
opened it in hexeditor. Checking range 0x28 - 0x39 gave me a board_id
(it was easy to find). It seems to be:
U12H189T00_NETGEAR

Unfortunately I don't know where to look for region. Does someone know
it's location in .chk file, or is there a application to automatically
extract it?
