Rafał Miłecki	608c7dccf2	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.

Rafał Miłecki	6292d1e354	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.

Sungbo Eo	4607f55439	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 Fixes: a6a0b252ba ("bcm4908: add sysupgrade support") Signed-off-by: Sungbo Eo <mans0n@gorani.run> (cherry picked from commit f432353850)	2021-11-05 14:13:46 +01:00
Rafał Miłecki	a5d457a0f4	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.
