[U-Boot] [PATCH 1/1] MX5:use common u-boot.lds of cpu layer
by Jason Liu 21 Oct '10

21 Oct '10

Remove u-boot.lds from mx5 and use the common u-boot.lds of cpu layer. This patch also fix the building errors: arch/arm/cpu/armv7/start.o: In function `_rel_dyn_start_ofs': arch/arm/cpu/armv7/start.S:283: undefined reference to `__rel_dyn_start' arch/arm/cpu/armv7/start.o: In function `_rel_dyn_end_ofs': arch/arm/cpu/armv7/start.S:283: undefined reference to `__rel_dyn_end' arch/arm/cpu/armv7/start.o: In function `_dynsym_start_ofs': arch/arm/cpu/armv7/start.S:283: undefined reference to `__dynsym_start' Signed-off-by: Jason Liu <r64343(a)freescale.com> --- arch/arm/cpu/armv7/mx5/u-boot.lds | 73 ------------------------------------- board/freescale/mx51evk/config.mk | 1 - board/ttcontrol/vision2/config.mk | 3 +- 3 files changed, 1 insertions(+), 76 deletions(-) diff --git a/arch/arm/cpu/armv7/mx5/u-boot.lds b/arch/arm/cpu/armv7/mx5/u-boot.lds deleted file mode 100644 index 55d6599..0000000 --- a/arch/arm/cpu/armv7/mx5/u-boot.lds +++ /dev/null @@ -1,73 +0,0 @@ -/* - * January 2004 - Changed to support H4 device - * Copyright (c) 2004 Texas Instruments - * - * (C) Copyright 2002 - * Gary Jennejohn, DENX Software Engineering, <gj(a)denx.de> - * - * (C) Copyright 2009 Freescale Semiconductor, Inc. - * - * 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.

[U-Boot] [PATCH] ARMV7: OMAP3: Add expansion board detection for Overo
by Steve Sakoman 20 Oct '10

20 Oct '10

ARMV7: OMAP3: Add expansion board detection for Overo Overo expansion boards contain an i2c eeprom to identify themselves. This patch adds code to read and parse the eeprom contents.
