本文大概介绍从一个已有的 linux 开发板， 移植到自己的产品的过程。假设开发板是 board-omap3devkit8000，自己的产品是 mytest
step1> 拷贝 /arch/arm/mach-omap2/board-omap3devkit8000.c ---> mytest.c
step2> /arch/arm/mach-omap2/Kconfig 增加如下几行config MACH_OMAP3_MYTEST bool "OMAP3 MYTEST board" depends on ARCH_OMAP3 && ARCH_OMAP34XX
step3> /arch/arm/mach-omap2/Makefile 增加如下几行
obj-$(CONFIG_MACH_OMAP3_MYTEST) +=board-omap3mytest.o / usb-musb.o usb-ehci.o / mmc-twl4030.o / twl4030-generic-scripts.o
step4> /arch/arm/tools/mach-types 增加最后一行. 注意，该数字要和 uboot 定义的一致
omap3_mytest MACH_OMAP3_MYTEST OMAP3_MYTEST 2004
step5> 编译
cd linux-2.6.28-omap
make distclean
make omap3_mytest_defconfig
make uImage
step6> 修改内核配置
cd linux-2.6.28-omap
cp arch/arm/configs/omap3_mytest_defconfig .config
make menuconfig
修改完后，保存，然后编译
make
make uImage
