Marian, All,

This is very interesting! :-)

It would be nice to have a defconfig for it.

Unfortunately, we can't cary such binary blobs.

Indeed, I woiuld guess that mlo and u-boot-old.bin come from u-boot,
and so they are covered by the GPLv2-or-later, so we can't have a
binary-only distribution for those files.

Please also provide a way to build them from source.

If that is not possible, then do not ship them, and adjust the
documentation to instriuct the user that they need a board with those
already installed.

Which brings us to the next point: the board directory should contain a
readme.txt that describes hos to build for the board, and how to install
the generated image files omn the board. See existing boards for some
examples, like board/zynq/readme.txt or board/pc/readme.txt.

That readme.txt would also be the place to list pointers to reference
manuals or documentation.

Regards,
Yann E. MORIN.
