MT7620N based boards should boot just fine. I have tested with one while developing the mediatek support.

It looks like you’ll need the WT3020-8M.dts file found in sys/gnu/dts/mips and use that when building with freebsd-wifi-build.
I am not sure if we’ll detect the full 64MB RAM - this would depend on U-Boot installed on the board. In case we only detect 32MB you’ll have to tweak the dts file a little, but let’s take this one step at a time.

I don’t think you’ll have to tweak anything in the kernel config - just tell freebsd-wifi-build to build you an image for ralink WT3020-8M.dts:
build ralink WT3020-8M.dts

This, as far as I remember, should be a good starting point.

Best wishes,
