Thanks for your feedback. I believe the current code already covers
the in-tree REFERENCE DT boards. Perhaps there is some board missing?

If you want to build an uImage for a certain DT board then perhaps you
can add it to the list with an incremental patch?

Or even better, use zImage instead of uImage, then we can have a
single binary for all boards.

So if you build the kernel for no board at all, either set the
LOADADDR variable as the help text says, or simply do not build for

Makes sense?
