From e7498281d3caec1141d7542ec494c4e4a1d404c9 Mon Sep 17 00:00:00 2001 From: Haavard Skinnemoen Date: Wed, 9 May 2007 02:33:47 -0700 Subject: Use common cpu_is_xxx() macros on AT91 and AVR32 Several drivers shared between AT91 and AVR32 chips use cpu_is_xxx() to handle CPU-specific differences. Currently, such code needs to be inside #ifdef CONFIG_ARCH_AT91 because the macros don't exist on AVR32. By defining the same macros on both AT91 and AVR32, these #ifdefs can be eliminated. Since the macros will evaluate to a constant value for CPUs that aren't supported by the current architecture, any code that is only needed on AT91 will be optimized away on AVR32 and vice versa.
