Booting
SD Boot
Partition the SD card in host with Single Falcon partitionc
git clone https://github.com/openedev/rootfs-sun64
cp -rf rootfs-sun64/* /media/jagan/rootfs/
cp /to/linux-next/arch/arm64/boot/Image /media/jagan/rootfs/boot
cp /to/linux-next/arch/arm64/boot/dts/allwinner/sun50i-a64-nanopi-a64.dtb /media/jagan/rootfs/boot
[Update boot/extlinux/extlinux.conf]
cd /to/u-boot
cat spl/sunxi-spl.bin u-boot.itb > u-boot-sunxi-with-spl.bin
dd if=u-boot-sunxi-with-spl.bin of=/dev/mmcblk0 bs=8k seek=1;
sync
Insert the SD card and power-on the board. See the Linux boot start from SPL
