u-boot-2016.11移植至S5PV210-单板配置

一、添加单板信息
1、
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"
#define S5PV210_ADDR_BASE       0xE0000000

/* S5PV210 */

#define S5PV210_WATCHDOG_BASE   0xE2700000
#define S5PV210_UART_BASE       0xE2900000
#define S5PV210_MMC_BASE        0xEB000000
#define S5PV210_SROMC_BASE      0xE8000000
#define S5PV210_DMC0_BASE       0xF0000000
#define S5PV210_DMC1_BASE       0xF1400000
#define S5PV210_VIC0_BASE       0xF2000000
#define S5PV210_VIC1_BASE       0xF2100000
#define S5PV210_VIC2_BASE       0xF2200000
#define SPPV210_VIC3_BASE       0xF2300000
#define S5PV210_NAND_BASE       0xB0E00000
/* modif by Sourcelink */
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;

case 0x02:
s5p_cpu_id = 0xc111;
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 S5PC110_##base;                          \
else                                                    \
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 */
