U-boot kernel transplantation steps

Linux 3.3.5 system porting

1. Copy mach-smdk6410.c under arch/arm/mach-s3c6410/ to mach-my6410.c;

2. Open Kconfig under arch/arm/mach-s3c6410/ and make a menu item based on MACH_SMDK6410:

config MACH_MY6410

bool "MY6410"

select CPU_S3C6410

select SAMSUNG_DEV_ADC

select S3C_DEV_HSMMC

select S3C_DEV_HSMMC1

select S3C_DEV_I2C1

Machine support for the Pillar MY6410

1. Open the arch/arm/tools/mach-types file. The machine ID stored here must be consistent with the ID in uboot. Copy line 283 and add it to the back and modify it to:

smdk6410 MACH_SMDK6410 SMDK6410 1626

xx6410 MACH_XX6410 XX6410 1626 The kernel can be started only when this machine ID is the same as the machine ID in UBOOT;

1. Modify the BSP file mach-my6410.c, the content is as follows:

Change all smdk6410 in the mach-mach-my6410.c file to my6410 (do not capitalize SMDK6410)

MACHINE_START(MY6410, "MY6410") //This should match MACH-MY6410 in Kconfig

1. Add obj-$(CONFIG_MACH_MY6410) += mach-my6410.o to the last line of Makefile in the current directory

2. Modify the top-level Makefile:

ARCH ?= arm

CROSS_COMPILE ?= /usr/local/arm/4.2.2-eabi/usr/bin/arm-linux-

1. Copy the s3c6400-defconfig file in arch/arm/configs/, save it as .config, configure the kernel to support EABI, select XX6410 board, save and exit;

2. Execute make menuconfig to configure the kernel:
