Tiny6410 的内核移植

Tiny6410 的内核移植

1下载linux-2.6.38的源码，ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.38.tar.bz2

2解压 tar xvfj /mnt/Ubuntu/linux-2.6.38.tar.bz2 -C .
3vi Makefile       191行改为    ARCH            ?= arm
4cp arch/arm/configs/s3c6400_defconfig .config（如果省略的话，后面会找不到System Type）
5make menuconfig
General setup->(/usr/4.5.1/bin/arm-linux-) Cross-compiler tool prefix    我将编译器解压到了/usr/4.5.1目录
     System Type->[*] MINI6410   选上，其他的可以去掉，不确定的可以参考友善之臂的

6     拷贝友善的drivers/mtd/nand/s3c_nand.c

      arch/arm/plat-samsung/include/plat/regs-nand.h

      drivers/mtd/nand/s3c_nand_mlc.fo

       
drivers/mtd/nand/nand_base.c 

到相应的文件夹下

7修改drivers/mtd/nand/Kconfig，我也不愿意改了，直接拷贝掉了

8drivers/mtd/nand/Makefile中20行增加
obj-$(CONFIG_MTD_NAND_S3C)            += s3c_nand.o

末尾再增加
S3C_NAND_MLC_SRC = $(shell ls drivers/mtd/nand/s3c_nand_mlc.c 2>/dev/null)
ifeq ($(S3C_NAND_MLC_SRC),)
obj-$(CONFIG_MTD_NAND_S3C)            += s3c_nand_mlc.fo
else
obj-$(CONFIG_MTD_NAND_S3C)            += s3c_nand_mlc.o
endif

这步要是不愿意改的话，直接拷贝覆盖即可

9然后再make
 menuconfig
