Is there some appropriate documentation on how boards.cfg is supposed to work?
Not that I'm aware of. Its a relatively recent change to U-Boot.
The latest u-boot.git still seems to have the P2020DS lines that I referenced in "Makefile", and it has no references at all to "P2020DS" in the "boards.cfg" file.
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
