5f05795aa7 bcm4908: sysupgrade: add pkgtb format support
BCM4908 devices with U-Boot use pkgtb firmware format. It's based on
U-Boot's FIT: DTB with configurations, images & embedded data.

This format contains bootfs, rootfs and optionally a first stage U-Boot
loader. Contained images need to be extracted & flashed.

Broadcom used two sets of firmwares: main & backup. It uses UBI volumes
"metadata1" & "metadata2" for storing U-Boot env variables with info
about flashed images.

30b168b9b8 bcm4908: sysupgrade: refactor handling different firmware formats
This results in setting format specific data (format info, extract
commands) in a single function. It should help maintaining sysupgrade
code.

This change has been tested on Asus GT-AC5300 and Netgear R8000P.

f432353850 bcm4908: fix calculation of new cferam index
The arithmetic expansion fails when idx becomes a two digit number.
Fix this by relying on expr command.

root@OpenWrt:/# echo $(((028 + 0) % 1000))
/bin/ash: arithmetic syntax error
root@OpenWrt:/# echo $(($(expr 028 + 0) % 1000))
28

a6a0b252ba bcm4908: add sysupgrade support
It supports flashing OpenWrt images (bootfs & UBI upgrade) as well as
vendor images (whole MTD partition write).

Upgrading cferom is unsupported. It requires copying device specific
data (like MAC) to target image before flashing.
