 EDK2 UEFI firmware for Rockchip RK3588 platforms
  https://github.com/edk2-porting/edk2-rk3588
  https://github.com/edk2-porting/edk2-rk3588/releases/download/v1.1/nanopc-t6_UEFI_Release_v1.1.img

  = EDK2 is on eMM
  = bootaa64.efi in FAT fs and NetBSD FFSs are on M.2 NVMe

  * EDK2 can be loaded from eMM or microSD
  * EDK2 can load bootaa64.efi from NVMe (or USB mass strage)
  * bootaa64.efi can load NetBSD kernel from NVMe (or USB mass strage)
  * NetBSD kernel can use NVMe (or USB mass strage) as root file system

  * and, NetBSD 10.1/aarch64 cannot use eMM nor microSD as root (yet).

 1) flash Linux image to microSD, boot it, write EDK2 image to eMM

    linux# dd of=/dev/mmcblk2  if=nanopc-t6_UEFI_Release_v1.1.img

 2) boot using USB mass strage (FAT bootaa64.efi + NetBSD FFS),
    prepare M.2 NVMe with gpt(8), newfs_msdos(8), newfs(8), .. etc.

 I use urtwn(4) for Wi-Fi. stable.
 on board rge0, rge1 at pci shows (six-zeros)

    rge0: Ethernet address 00:00:00:00:00:00
