Adding support for Zyxel lte 3301 q222

would it be possible to add support for it? i think that the kernel should support most of the parts that it uses. just dont really know how to make those openwrt specific config files that are needed to build the rom. dmesg output of it is here if it helps..

It looks like it's an MT7620 SoC, so should be possible yes. Already quite a few devices with that SoC that have OpenWrt support.

whats the format that is used for the partition numbers in the openwrt build files? all the supported devices have some short id but that dmesg output has a long number.

Hex preferred -- It's compiled from the DTS into a DTB and then used by the MTD drivers. How it is printed is purely a function of the code that accesses the data from the running system.

Joining here to kindly ask the developers to look into the possibility of creating builds for Q222 as well as M209 models of the LTE3301. It's impossible to underestimate VPN/IPSec possibility for the LTE router dealing mainly with private IPs...
