[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.
