From 3b328c98093702c584692bffabd440800b383d73 Mon Sep 17 00:00:00 2001 From: Haavard Skinnemoen Date: Tue, 13 Mar 2007 15:30:38 +0100 Subject: [AVR32] Clean up cpu identification and add features bitmap Clean up the cpu identification code, using definitions from instead of hardcoded constants. Also, add a features bitmap to struct avr32_cpuinfo to allow other code to make decisions based upon what the running cpu is actually capable of.
