From 9d0412680e6c7b685ee466842047bcfb924d6dc5 Mon Sep 17 00:00:00 2001 From: Andrew Victor Date: Mon, 5 Feb 2007 11:42:07 +0100 Subject: [ARM] 4124/1: Rename mach-at91rm9200 and arch-at91rm9200 directories Now that Linux includes support for the Atmel AT91SAM9260 and AT91SAM9261 processors in addition to the original Atmel AT91RM9200 (with support for more AT91 processors pending), the "mach-at91rm9200" and "arch-at91rm9200" directories should be renamed to indicate their more generic nature. The following git commands should be run BEFORE applying this patch: git-mv arch/arm/mach-at91rm9200 arch/arm/mach-at91 git-mv include/asm-arm/arch-at91rm9200 include/asm-arm/arch-at91 Signed-off-by: Andrew Victor Signed-off-by: Russell King --- arch/arm/mach-at91/board-sam9260ek.c | 202 +++++++++++++++++++++++++++++++++++ 1 file changed, 202 insertions(+) create mode 100644 arch/arm/mach-at91/board-sam9260ek.c (limited to 'arch/arm/mach-at91/board-sam9260ek.c') diff --git a/arch/arm/mach-at91/board-sam9260ek.c b/arch/arm/mach-at91/board-sam9260ek.c new file mode 100644 index 00000000000..6ae272d224e --- /dev/null +++ b/arch/arm/mach-at91/board-sam9260ek.c @@ -0,0 +1,202 @@ +/* + * linux/arch/arm/mach-at91/board-ek.c + * + * Copyright (C) 2005 SAN People + * Copyright (C) 2006 Atmel + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
