for one define only ???

Do you have plans to add more stuff here ? Do you have any other files
that might need this define besides the main board-file ??

Looks unnecessary to add yet another header for one define only. Moving
to the board-file would be more acceptable.

Yes, it's more like a placeholder for future patches. I plan to add a
function prototype and some more GPIOs. I also plan adding another
board file for input stuff (board-omap3pandora-input.c), as pandora
has lots of GPIO buttons with full qwerty keypad, and I don't want to
clutter the main board file with large arrays of structures.
If this is not acceptable I can stuff everything into board-omap3pandora.c

I think tony has the final word here, but generally the other board
files have the keypad stuff in the main board file (board-n800.c,
board-3430sdp.c, board-2430sdp.c, etc)

About the defines, it's only nice to put them in the header iff you
need to use the same define on two (or more) different files. Otherwise,
you can make the defines local to the file that needs them :-)

Well the header should be there only if needed for other boards.
