Installing Arch Linux AArch64 on the NanoPi R2S

There is current no support for the NanoPi R2S in ArchLinuxArm, but it's possible to run it using the generic aarch64 installation.

Prepare sd-card/image

1. Copy bootloader and uBoot from an armbian image using for the NanoPi R2S using dd (sectors 32 to 32767) everything before the partition, except the partition table).
2. Create an ext4 partition on /dev/mmcblk0p1 at offset of 32768 sectors (16384 KiB):

Device         Boot Start      End  Sectors  Size Id Type
