From 9b6553cd01ce3ea7a6a532f7b7e62e3535d6b102 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Sun, 2 Apr 2006 17:46:30 +0100 Subject: [ARM] 3433/1: ARM: OMAP: 8/8 Update board files Patch from Tony Lindgren This patch syncs OMAP board support with linux-omap tree. The highlights of the patch are: - Add support for Nokia 770 by Juha Yrjola - Add support for Samsung Apollon by Kyungmin Park - Add support for Amstrad E3 videophone by Jonathan McDowell - Remove board-netstar.c board support as requested by Ladislav Michl - Do platform_device registration in board files by Komal Shah et al.
