u-boot-2016.11移植至S5PV210-单板配置

一、添加单板信息

1. 拷贝单板

    cp -r board/samsung/smdkc100 board/samsung/smdkv210

2. 进入smdkv210下

	cd board/samsung/smdkv210/
	mv smdkc100.c smdkv210.c

3. 修改Kconfig

	if TARGET_SMDKV210

	config SYS_BOARD
        	default "smdkv210"
 
	config SYS_VENDOR
        	default "samsung"
 
	config SYS_SOC
       	 	default "s5pv210"
 
	config SYS_CONFIG_NAME
        	default "smdkv210"
 
	endif  			

4. 修改MAINTAINERS

SMDKV210 BOARD
M:      Minkyu Kang <mk7.kang@samsung.com>
S:      Maintained
F:      board/samsung/smdkv210/
F:      include/configs/smdkv210.h
F:      configs/smdkv210_defconfig

5. 修改Makefile

obj-y   := smdkv210.o
obj-$(CONFIG_SAMSUNG_ONENAND)   += onenand.o
obj-y   += lowlevel_init.o

6. 根据MAINTAINERS修改inclu/configs/smdkv210.h 和configs/smdkv210_defconfig

cp include/configs/smdkc100.h include/configs/smdkv210.h
cp configs/smdkc100_defconfig configs/smdkv210_defconfig 

7. 修改smdkv210_defconfig

CONFIG_ARM=y
CONFIG_ARCH_S5PV210=y
CONFIG_TARGET_SMDKV210=y
CONFIG_IDENT_STRING=" for SMDKV210"
CONFIG_DEFAULT_DEVICE_TREE="s5pv210-smdkv210"
CONFIG_BOOTDELAY=3
CONFIG_HUSH_PARSER=y
CONFIG_SYS_PROMPT="SMDKV210 # "

# CONFIG_CMD_IMLS is not set
# CONFIG_CMD_FLASH is not set
# CONFIG_CMD_SETEXPR is not set
CONFIG_CMD_CACHE=y
CONFIG_CMD_FAT=y

二、添加S5PV210信息

1. 进入arch/arn目录下

cd arch/arm
vim Kconfig

# add by Sourcelink
config ARCH_S5PV210
        bool "Samsung S5PV210"
        select CPU_V7
        select DM
        select DM_SERIAL
        select DM_GPIO
 
# add by Sourcelink
source "arch/arm/mach-s5pv210/Kconfig"

2. 修改Makefile

vim Makefile
 
# add by Sourcelink
machine-$(CONFIG_ARCH_S5PV210)          += s5pv210

3. 复制mach-s5pc1xx

cp -r mach-s5pc1xx mach-s5pv210

4. 修改mach-s5pv210目录下Kconfig

cd mach-s5pv210/
 
vim Kconfig
 
if ARCH_S5PV210
 
choice
        prompt "S5PV210 board select"
        optional
 
#config TARGET_S5P_GONI
#       bool "S5P Goni board"
#       select OF_CONTROL
 
config TARGET_SMDKV210
        bool "Support smdkv210 board"
        select OF_CONTROL
 
endchoice
 
config SYS_SOC
        default "s5pv210"
 
source "board/samsung/goni/Kconfig"
source "board/samsung/smdkv210/Kconfig"
 
endif

4. 修改cpu.h

cd include/mach
 
vim cpu.h
#ifndef _S5PV210_CPU_H
#define _S5PV210_CPU_H
 
#define S5P_CPU_NAME            "S5P"

static inline void s5p_set_cpu_id(void)
{
        int id = 0;
        s5p_cpu_id = readl(S5PV210_PRO_ID);
        s5p_cpu_rev = s5p_cpu_id & 0x000000FF;
        id = (s5p_cpu_id & 0xFFFFF000) >> 12;
        if (id == 0x43110) {
                id = s5p_cpu_id & 0x0F;
                switch (id) {
                        case 0x00:
                                s5p_cpu_id = 0x56210;
                        break;
 
                        case 0x01:
                                s5p_cpu_id = 0xc110;
                        break;

                        break;
 
                        default : break;
                }
        }
}
/* add by Sourcelink */
IS_SAMSUNG_TYPE(s5pv210, 0x56210)
 
/* modif by Sourcelink */
#define SAMSUNG_BASE(device, base)                              \
static inline unsigned int samsung_get_base_##device(void)      \
{                                                               \
        if (cpu_is_s5pv210())                                   \
                return S5PV210_##base;                          \
        else if (cpu_is_s5pc100())                              \
                return S5PC100_##base;                          \
        else if (cpu_is_s5pc110())                              \

                return 0;                                       \
}

5. 修改board/samsung/smdkv210/lowlevel_init.S 将里面S5PC100全部替换为S5PV210

6. 添加soc

cd arch/arm/cpu/armv7
vim Makefile
# modif by Sourcelink
ifneq (,$(filter s5pv210 s5pc1xx exynos,$(SOC)))
obj-y += s5p-common/
endif

7. 添加设备树

cd arch/arm/dts/
cp s5pc1xx-smdkc100.dts  s5pv210-tsmdkv210.dts

8. 修改Makefile

vim Makefile
# add by Sourcelink
dtb-$(CONFIG_S5PV210) += s5pv210-smdkv210.dtb

9. 添加CONFIG_S5P210宏

cd include/configs/
vim smdkv210.h
#define CONFIG_S5PV210          1       /* which is in a S5PC100 */
