Compilation
We first need to move the config file by running
cp arch/arm/configs/bcmrpi_cutdown_defconfig .config # 看情况
Then configure the kernel build
make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- oldconfig # 看情况
Optional: Customise the build using menuconfig
make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- menuconfig
Then run the compilation
make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- -k
