Reported these to checkpatch maintainer. V2: * Removed the label __flash_image_end because _end serves the same purpose after rebasing to latest mainline V3: * Moved CONFIG_SYS_TEXT_BASE to board config header and deleted config.mk * Changes for the struct based register accesses * Removed usage of modify_reg_32() macro * omap4_rev_string() reference changed to omap_rev_string() * Folded the patches for linker script changes and console support into this patch * Improved commit message V4: * Changed the CONFIG_SYS_SPL_* config flags to: CONFIG_SPL_* * Changed the name omap4_rev_string used in spl.c as this file is common for OMAP3/4 --- arch/arm/cpu/armv7/Makefile | 7 ++- arch/arm/cpu/armv7/omap-common/Makefile | 4 + arch/arm/cpu/armv7/omap-common/spl.c | 82 +++++++++++++++++++++++++ arch/arm/cpu/armv7/omap-common/u-boot-spl.lds | 62 +++++++++++++++++++ arch/arm/cpu/armv7/omap4/Makefile | 5 +- arch/arm/cpu/armv7/omap4/board.c | 7 ++ arch/arm/cpu/armv7/omap4/clocks.c | 33 ++++++++++ arch/arm/include/asm/arch-omap4/sys_proto.h | 1 + arch/arm/include/asm/omap_common.h | 2 + board/ti/panda/Makefile | 2 + board/ti/panda/config.mk | 31 --------- board/ti/sdp4430/Makefile | 2 + board/ti/sdp4430/config.mk | 31 --------- include/configs/omap4_panda.h | 26 ++++++++ include/configs/omap4_sdp4430.h | 26 ++++++++ 15 files changed, 257 insertions(+), 64 deletions(-) create mode 100644 arch/arm/cpu/armv7/omap-common/spl.c create mode 100644 arch/arm/cpu/armv7/omap-common/u-boot-spl.lds delete mode 100644 board/ti/panda/config.mk delete mode 100644 board/ti/sdp4430/config.mk diff --git a/arch/arm/cpu/armv7/Makefile b/arch/arm/cpu/armv7/Makefile index 299792a..92a5a96 100644 --- a/arch/arm/cpu/armv7/Makefile +++ b/arch/arm/cpu/armv7/Makefile @@ -26,7 +26,12 @@ include $(TOPDIR)/config.mk LIB = $(obj)lib$(CPU).o START := start.o -COBJS := cpu.o cache_v7.o + +ifndef CONFIG_SPL_BUILD +COBJS += cache_v7.o +COBJS += cpu.o +endif + COBJS += syslib.o SRCS := $(START:.o=.S) $(COBJS:.o=.c) diff --git a/arch/arm/cpu/armv7/omap-common/Makefile b/arch/arm/cpu/armv7/omap-common/Makefile index 8f698f8..0708796 100644 --- a/arch/arm/cpu/armv7/omap-common/Makefile +++ b/arch/arm/cpu/armv7/omap-common/Makefile @@ -30,6 +30,10 @@ SOBJS := reset.o COBJS := timer.o COBJS += utils.o +ifdef CONFIG_SPL_BUILD +COBJS += spl.o +endif + SRCS := $(SOBJS:.o=.S) $(COBJS:.o=.c) OBJS := $(addprefix $(obj),$(SOBJS) $(COBJS)) diff --git a/arch/arm/cpu/armv7/omap-common/spl.c b/arch/arm/cpu/armv7/omap-common/spl.c new file mode 100644 index 0000000..b201543 --- /dev/null +++ b/arch/arm/cpu/armv7/omap-common/spl.c @@ -0,0 +1,82 @@ +/* + * (C) Copyright 2010 + * Texas Instruments, + * + * Aneesh V + * + * 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.
