That's the goal for this release, to make them look similar.

I was pondering whether there's some way to factor out the common parts,
or maybe even replace some of the defconfigs with a placeholder for
compatibility reasons and just go with one full defconfig for all SoCs
(H3/M3W/M3N) that can be on such a board.

I'd still like to be able to do "make soc_board_defconfig ; make"
without having to rack my brain which other .cfg files I need to append.
I didn't find a good solution for this however. Do you know of one ?
