NACK. At least in this version. Please double check all the kirkwood
boards (taken from boards.cfg):

I have noticed that board ib62x0 is not in this patch. I have tested
this patch with my ib62x0 board and it works. This is the patch I have
added:

diff --git a/board/raidsonic/ib62x0/ib62x0.c b/board/raidsonic/ib62x0/ib62x0.c

-	u32 kwmpp_config[] = {

 		MPP0_NF_IO2,
 		MPP1_NF_IO3,
 		MPP2_NF_IO4,

Also you should note that this patch should be applied after your
patches for lsxl board.
