[U-Boot] [PATCH] board: Remove overlooked vestiges of "dave" board.

Thu Apr 14 12:15:07 CEST 2016


Apparently, all "dave"-related vendor content was removed in commit
5344cc1a82fcc2817d4671696b3939b0dfa4323e; remove remaining directory
board/dave/, which consists solely of board/dave/common/flash.c.

Signed-off-by: Robert P. J. Day <rpjday at crashcourse.ca>

---

  there is also a board/davedenx/aria/, i have no idea if that is
related.
