Since FSMC is a standard IP and it supports different memory interfaces the
FSMC
grammar
'interfaces the' - 'interfaces; the'
is supported independent of spear platform and spear is configured to use that
driver for interfacing with the NAND device
Describe that because the common interface is used,
the spear specific files
arch/arm/include/asm/arch-spear/spr_nand.h,
drivers/mtd/nand/spr_nand.c
Have been removed and replaced
