FWIW, I've looked at this code and discussed it with Ryan. The first
thing is that it adds too much stuff in uboot/uboot.mk and
uboot/Config.in, so I've created a patch that moves platform-specific
stuff into other .mk and Config.in files within boot/uboot/, on top of
which I've changed Ryan's patch. It makes things more reasonable I
believe.

See:

However, I've asked Ryan to take some significant portions of his cover
letter, and use that to extend the Config.in help text to explain how
this thing can/should be used, and under what conditions.

I guess Ryan will resubmit the set of 3 patches when he is done with
this Config.in help text writing.

Best regards,

Thomas
