I'm looking for ideas/comments on how to best integrate configuration tweaks for specific sunxi boards into the U-Boot (build) ecosystem. An example would be adding U-Boot support for GPIO-driven LEDs (and the "led" command), which I'm demonstrating here for the Banana Pi.
My current line of thought is: Have sunxi-common.h include a separate sunxi-boards.h, to prevent pollution of the "master" include (in case the file later grows to accomodate multiple configurations). sunxi-boards.h in turn could tweak configuration settings as needed, or pull in further includes, depending on board-specific definitions. The latter would probably originate from the boards' *_defconfig files.
Regards, B. Nortmann
