Please split this patch into 2 patches, one for each board

Can you please add for the 2 upcoming board patches a description
of the boards, which IOs they have, what they are meant for and an URL
to the product? You can look at a git log of any other recent board
commit.

The 2 lines above should be part of the previous patches for the

Do we need any special cable connection like USB or uart?

Is this mandatory ^^^? Or can we let the user to choose the libc?

We're very close to 5.19 release, so I ask you to send the final
patches with 5.19

Do we need such big rootfs? Usually 120M is the used default.

I don't know the boot-flow of this processor, so you need the SPL and
then again another SPL and u-boot too?
