Any further thoughts from anyone on the best way to add support for
platforms like this?  I've got a local patch adding a .dts for an
ast2400 system that differs from ast2400-evb.dts even less than the
above (just switching the console to a different UART and making a
similar pinctrl tweak for RGMII on mac1).  I was about to post it, but
then saw this thread, so I figured I'd hold off if there's likely to be
a Kconfig-based way of achieving that soon.


Thanks,
