From d4fc6012fd0a5c211b825691f44b06f8032c0551 Mon Sep 17 00:00:00 2001 From: Peter Pearse Date: Tue, 14 Aug 2007 10:10:52 +0100 Subject: [PATCH 1/6] Add MACH_TYPE records for several AT91 boards. Merge to two at45.c files into a common file, split to at45.c and spi.c Fix spelling error in DM9161 PHY Support. Initialize at91rm9200 board (and set LED). Add PIO control for at91rm9200dk LEDs and Mux. Change dataflash partition boundaries to be compatible with Linux 2.6.
