[嵌入式]移植到純淨版本的uboot1.1.6過程–OK6410

學習OK6410時發現uboot1.1.6_256M中的檔案與uboot1.1.6源中的檔案配置變化很大，所以，我這裡自己在uboot1.1.6中添加，並且己經成功。

1. 主Makefile檔案

.........................
1.1 lib支援庫
在LIBS += drivers/nand_legacy/libnand_legacy.a下面
# add to support onenand. by scsuh
LIBS += drivers/onenand/libonenand.a
ifeq ($(CPU),mpc83xx)
LIBS += drivers/qe/qe.a
endif

1.2 交叉編譯工具
CROSS_COMPILE=/usr/local/arm/4.2.2-eabi/usr/bin/arm-linux-
 
1.3 配置環境
smdk6410_config :unconfig
@$(MKCONFIG) $(@:_config=) arm s3c64xx smdk6410 samsung s3c6410

  可以得到ARCH=arm;CPU=s3c64xx;BOARD=smdk6410;vendor=samsung;soc=s3c6410;

1.4 mkconfig添加
if [ "$3" = "s3c64xx" ] ; then
rm -f regs.h
ln -s $6.h regs.h
rm -f asm-$2/arch
ln -s arch-$3 asm-$2/arch
fi

2.添加檔案
board/samsung/smdk6410/*;
include/configs/smdk6410.h; ->
cpu/s3c64xx/*;
include/s3c6410.h-->regs.h(linux shell: ln -s $6.h regs.h)
include/s3c64x0.h
include/s3c6400.h

include/asm-arm/arch-s3c64xx/*; ->通過mkconfig會建立連結檔案arch

修改檔案

include/linux/mtd/*;
include/linux/mmc/*;
include/movi.h
include/div64.h
drivers/mtd/*;
drivers/nand/*;
drivers/onenand/*;
drivers/qe/*;
common/cmd_nand.c
common/cmd_date.c
rtc/s3c64xx_rtc.c
lib_generic/div64.c

4.編譯

make smdk6410_config

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

附：有可能出現: undefined reference to 'raise'

就替換lib_arm/*;

5.啟動kernel
替換common檔案 12個新增
cmd_movi.c
cmd_onenand.c
cmd_usbd.c
cyclon2.c
env_movi.c
env_onenand.c
....
還須修改cmd_bootm.c
