From 8eb0ee6a649d09a41155bf6c9dbd4d531ed41f9e Mon Sep 17 00:00:00 2001 From: Vipin KUMAR Date: Mon, 7 May 2012 13:06:43 +0530 Subject: [PATCH] SPEAr: Add macb driver support for spear310 and spear320 SPEAr310 and SPEAr320 SoCs have an extra ethernet controller. The driver for this device is already supported by u-boot, so configuring board configuration file and defining base addresses etc to make use of the common driver Signed-off-by: Vipin Kumar Signed-off-by: Amit Virdi Signed-off-by: Stefan Roese --- arch/arm/include/asm/arch-spear/clk.h | 27 ++++++++++++++++++++++ arch/arm/include/asm/arch-spear/hardware.h | 7 ++++++ board/spear/spear310/spear310.c | 25 +++++++++++++++++--- board/spear/spear320/spear320.c | 12 +++++++--- include/configs/spear3xx.h | 13 +++++++++++ 5 files changed, 78 insertions(+), 6 deletions(-) create mode 100644 arch/arm/include/asm/arch-spear/clk.h diff --git a/arch/arm/include/asm/arch-spear/clk.h b/arch/arm/include/asm/arch-spear/clk.h new file mode 100644 index 0000000000..a45ec1861c --- /dev/null +++ b/arch/arm/include/asm/arch-spear/clk.h @@ -0,0 +1,27 @@ +/* + * (C) Copyright 2010 + * Vipin Kumar, STMicroelectronics, + * + * See file CREDITS for list of people who contributed to this + * project. + * + * 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.
