Raspberry pi 3 64bit BCM2837

Whenever NOOBs installed onto sdcard and putting 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.

**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

Mention these two line into config.txt because other than bcm2708-rpi-3-b.dtb, we must have to mention it 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.
