From ba854e18413d2d827f050984edeb8286c3335895 Mon Sep 17 00:00:00 2001 From: Andrew Victor Date: Wed, 5 Jul 2006 17:22:52 +0100 Subject: [ARM] 3711/1: AT91 timer update Patch from Andrew Victor The AIC interrupt controller is the same on the Atmel AT91RM9200, AT91SAM9261 and AT91SAM9260 processors. This patch removes any RM9200-specific naming from the IRQ driver, and moves the AT91RM9200's default IRQ priority table into at91rm9200.c.

Resolve this by using machine_is_xxx(). Also, for the CLCD, despite how the code looks, both the AB and PB access the same location to control the clock rate - it's just called something different between the two board versions. Invent our own name for this location and use it unconditionally.

All archs define set_wmb(var, value) to do { var = value; wmb(); } while(0) except ia64 and sparc which use a mb() instead. But this is still moot since it is not used anyway.
