obj-$(CONFIG_MACH_NCP) += mach-ncp.o
obj-$(CONFIG_MACH_HMT) += mach-hmt.o
obj-$(CONFIG_MACH_SMARTQ) += mach-smartq.o
obj-$(CONFIG_MACH_SMARTQ5) += mach-smartq5.o
obj-$(CONFIG_MACH_SMARTQ7) += mach-smartq7.o
三、About machine Number
打开arch/arm/tools/mach-types文件定位到217行左右,修改如下
at91sam9g20ek MACH_AT91SAM9G20EK AT91SAM9G20EK 1624
qt6410 MACH_QT6410 QT6410 1626
u300 MACH_U300 U300 1627
这需要两者相匹配，如果内核的机器码和bootloader 传入的不匹配，就会经常出现下面的错误：
Uncompressing Linux................................................................................................................................. done, booting
the kernel. 不动了
接着修改linux-2.6.39/arch/arm/mach-s3c64xx/qt6410.c定位到文件末尾处
四、配置、编译测试
root@bootloader:/home/eilian/development/Linux/linux-2.6.39#cp arch/arm/configs/s3c6400_defconfig .config
root@bootloader:/home/eilian/development/Linux/linux-2.6.39#make menuconfig
出现下图所示内核配置根菜单
设置完后退出
root@bootloader:/home/eilian/development/Linux/linux-2.6.39#make uImage
等待若干久后出现
SYSMAP .tmp_System.map
