From 99fa97e955f642deedb9f2de38e0215a8b3a40ac Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Andreas=20Bie=C3=9Fmann?= Date: Mon, 18 Oct 2010 22:58:29 +0200 Subject: at91rm9200ek: convert to at91 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch removes some functionality from at91rm9200ek board but the remaining functionality does now work with newer at91 code and arm-relocation. Currently missing features are: - dataflash booting (due to missing HW for testing) - MMC/SD-Card - first stage bootloader support is completely removed (not needed for NOR) Cause this board was (some days ago) reference for all at91rm9200 based boards this should be a good starting point to convert all remaining at91rm9200 borads to at91 code. Aside from that this is a good base to get some drivers between at91sam/at91rm/avr32 merged.
