Prepare SD

Transfer the following files from the firmware/boot directory to the Raspberry pi /boot directory:

   bootcode.bin
   fixup.dat
   start.elf

cp firmware/hardfp/opt/ /media/root/opt/ -rf

build

make mrproper
cp arch/arm/configs/bcmrpi_defconfig .config
export CCPREFIX=/path/to/your/compiler/binary/prefix-of-binary-
make ARCH=arm CROSS_COMPILE=${CCPREFIX} oldconfig
make ARCH=arm CROSS_COMPILE=${CCPREFIX}

libraries

pi@raspberrypi:~$ ls /lib/

Update kernel in Raspbian

Get source

$ git clone --depth=1 https://github.com/raspberrypi/linux
$ sudo apt-get install bc

Raspberry Pi 1 (or Compute Module) Default Build Configuration

$ cd linux
$ KERNEL=kernel
$ make bcmrpi_defconfig

Raspberry Pi 2 Default Build Configuration

$ cd linux
$ KERNEL=kernel7
$ make bcm2709_defconfig

Build and install the kernel, modules and Device Tree blobs

$ make zImage modules dtbs
$ sudo make modules_install
$ sudo cp arch/arm/boot/dts/*.dtb /boot/
$ sudo cp arch/arm/boot/dts/overlays/*.dtb* /boot/overlays/
$ sudo cp arch/arm/boot/dts/overlays/README /boot/overlays/
$ sudo scripts/mkknlimg arch/arm/boot/zImage /boot/$KERNEL.img

Note: On a Raspberry Pi 2, adding -j4 (make -j4 zImage modules dtbs) splits the work between all four cores, speeding up compilation significantly.

Cross Compile

$ git clone https://github.com/raspberrypi/tools
add /tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin to your $PATH
make bcm2709_defconfig ARCH=arm
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage modules dtbs -j4
