Subject:	"1.at45":(3 of  4)     [PATCH] [ARM] 	Merge to two files into a common file and split.

CHANGELOG:
    [PATCH] [ARM] 	Merge to two files into a common file and split.

    Merge to two virtually identical files.
	"board/at91rm9200dk/at45.c"
	"board/cmc_pu2/at45.c" (one bug fixed first)
    into "driver/at45.c" then move at91rm9200 specific functions from
    "driver/at45.c" to:	"cpu/arm920t/at91rm9200/spi.c	
    Update Makefiles to reflect change

    Patch generated from files:
          board_cmc_pu2_at45.c.patch
          board_cmc_pu2_Makefile.patch
