So it was removed back in July [1]. what is needed is someone to
actively maintain the SoC, the DM_I2C pieces are likely the first step
but there will be, likely minor, ongoing work needed. Fixing just one
thing is likely straight forward but it's more about an ongoing,
likely quite small, commitment of helping keep the platform up to date
and ensure it's continues to work.

If you're prepared to do that the first step would be to do a patch
set that basically reverts the removal and updates for any changes to
U-Boot since it was dropped in July, which would be at least be for
the early boot rename (SPL/TPL -> XPL) pieces and the DM_I2C
conversion.
