Boot up steps for Raspberry pi 3 Kernel-4.12.3 64bit ARMv8 using bcm2837 dts.

Whenever NOOBs installed into sdcard and inserting into pi-3 board, by-default pi-3 board booting up with bcm2708-rpi-3-b.dtb kernel-4.4.38 32bit ARMv7.

But procedure is different If you want to boot up kernel-4.12.3 64bit ARMv8 on pi-3.

Note : Keep remain sdcard with noobs installed and just replace below files only. Now follow below steps.

Step1: Cross compile your kernel with 64bit.
       # make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- bcmrpi3_defconfig
       # make -j 12 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-

Step2: Copy File into sdcard boot dir.
       # cp arch/arm64/boot/dts/broadcom/bcm2837-rpi-3-b.dtb  /media/(path to sdcard)/boot/
       # cp arch/arm64/boot/dts/overlays/*.dtbo /media/(path to sdcard)/boot/overlays/
       # cp arch/arm64/boot/Image /media/(path to sdcard)/boot/kernel8.img

Step3: Copy modules into sdcard root dir.
       # make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-  INSTALL_MOD_PATH=/(path to sdcard)/root/ modules_install

Step4: Mention these two line into "config.txt". without it won't boot up.

       device_tree=bcm2837-rpi-3-b.dtb
       kernel=kernel8.img

One caveat. If you are making changes to upstream code (i.e. with no changes specific to Raspberry Pi devices), then it's best to submit your changes upstream, then when they are accepted, we can cherry-pick them back to our branches here.
