Should we introduce mach- > directories or not? > OK: Option 4: How about this guys? include/board-common is an actual directory and instead of headers being located in board/$(VENDOR)/common or board/$(VENDOR)/common/include, we move the common headers to include/board/$(VENDOR)/ Directory. This will make the usage as follows: #include <$(VENDOR)/xyz.h> I know this does not exactly meet Simon's suggestion here of being identifiably board-common/xyz.h -> but at least knowing the prefix as vendor name implies a board common header.
