Not that I'm aware of.  Its a relatively recent change to U-Boot.

It looks like the top-level Makefile is still required for boards that
support multiple configs, eg 'make P2020DS_36BIT' will configure U-Boot
to compile a 36-bit addressable U-Boot image while 'make P2020DS' will
configure a 32-bit addressable U-Boot image, but they both use the same
Makefile rule with some fancy parsing.  So I guess if you have a need
for both a 32 and 36bit version of U-Boot you'll to modify the Makefile
like your original patch did unfortunately.  If you don't need to
support both U-Boot configs, you can go the route of other similar
boards that are only in boards.cfg, eg P4080DS, P1022DS, XPedite5370,
etc.

Best,
Peter
