Since Julien Masson is marked as maintainer here, can we guarantee he
will be doing some testing/reviewing on patches for this particular
board?

If not, maybe find another maintainer.

Could we add this board to the MediaTek board documentation?

https://docs.u-boot.org/en/latest/board/mediatek/index.html

I know that doc is a bit outdated but it would be nice to improve it and
list this board.

For me, that can be done in a future series/improvement.

Thanks
Mattijs

Hi Mattijs,

I checked with Julien Masson and he wants to be maintainers, but I
also added Macpaul Lin from Mediatek, as co-maintainer.

I forwarded the request to Mediatek internal teams, and they will
handle this internally.
With the Lunar new year vacation coming they won't be able to do this
before end of February.
Same for other new coming boards.

Julien
