Well those you can easily optimize out by not compiling in those devices. > > b) we took reference from board-rx51-peripherals.c wherein some parts of the > board file can be moved out to a new file > > If you still think we need to merge, then let us know. > We are open to suggestions/changes. Well the reason for separate board-*-peripheral-whatever.c files is that they're intended to be shared with other board-*.c files. Currently n8x0 and rx51 share devices. In general, we should try to do generic platform init files, like gpmc-onenand.c and gpmc-smc91x.c. Then I see need for gpmc-sdp-flash.c that's shared between 2430 and 3430 sdp at least. So yeah, for zoom2, I'd rather see just board-zoom2.c for now. But if you create some other board that uses the same debug board functions, then there could be a separate zoom-debugboard.c.
