From 79da7a610a1f81b51a1a77e2ac27438d7a5c5124 Mon Sep 17 00:00:00 2001 From: Andrew Victor Date: Thu, 30 Nov 2006 11:58:14 +0100 Subject: [ARM] 3947/1: AT91: cpu_is_XXX macro's This patch replaces the arch_identify() in system.h with a set of cpu_is_XXX() macro's. This allows for compile-time checking of the target AT91 processor. Original patch from David Brownell.
