From 36f28f8a9605ee5dcfa330482cfc62171261af97 Mon Sep 17 00:00:00 2001 From: Haavard Skinnemoen Date: Mon, 29 Oct 2007 13:09:56 +0100 Subject: AVR32: Rename at32ap7000 -> at32ap700x The SoC-specific code for all the AT32AP700x CPUs is practically identical; the only difference is that some chips have less features than others. By doing this rename, we can add support for the AP7000 derivatives simply by making some features conditional.
