Add support for b2368 (MT7621 +WDU1CPM1AWB)

hello all,
I have a ramips platform 4g router b2368
the version I have is b2368-57 (which is odu + idu)
Main specifications for the odu

how to compile openwrt for this router?

Check https://openwrt.org/toh/start if it's already listed as supported, if that isn't the case, someone -read you- will have to do the leg-work to get it ported to OpenWrt (https://openwrt.org/docs/guide-developer/add.new.device).
