ARM: OMAP: Change omap_cf.c and omap_nor.c to use omap_readw/writew instead of __REG
Change omap_cf.c and omap_nor.c to use omap_readw/writew instead of __REG. This is needed for multi-omap in the future. Cc: David Brownell <david-b@pacbell.net> Cc: linux-pcmcia@lists.infradead.org Cc: linux-mtd@lists.infradead.org Signed-off-by: Tony Lindren <tony@atomide.com>
