OK, good.  Can you and Marek please coordinate on:
- Updating MAINTAINERS files
- Dropping the boards that won't be supported moving forward (even if
  you can't mainline the custom board, there must be a ref platform you
  have/use, yes?).

And Michael, can you please subscribe to the u-boot-maintainers list?

Jagan, was there an old patch to try and convert this driver that may be
of help to Michael?  Thanks!
