ARM: OMAP: Allow platforms to hook reset cleanly This adds a clean method to allow platforms to hook into the reset code if they require to. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Tony Lindgren <tony@atomide.com>

/*
* OMAP1 reset support
*/
#include <linux/kernel.h>
#include <linux/io.h>
#include <plat/prcm.h>
ARM: OMAP1: Move most of plat/io.h into local iomap.h There's no need to have these in plat/io.h. While at it, clean up the includes to group them like they typically are grouped. Signed-off-by: Tony Lindgren <tony@atomide.com>

#include <mach/hardware.h>
ARM: OMAP: add includes for missing prototypes Several C files in arch/arm/mach-omap* and arch/arm/plat-omap declare functions that are used by other files, but don't include the header file where the prototype is declared. This results in the following warnings from sparse: arch/arm/mach-omap2/irq.c:114:5: warning: symbol 'omap_irq_pending' was not declared.
