On the FAT partition:

  /BOOT/EFI/bootarm.efi
  /dtb/am335x-boneblack.dtb

In the EFI bootloader, you can get a list of devices with the 'dev' 
command:

  > dev
  hd0 (29 GB): VenHw(E61D73B9-A384-4ACC-AEAB-82E828F3628B)/Usb(0x6,0x0)
    hd0a (29 GB): 4.2BSD
    hd0e (80 MB): MSDOS
  hd1 (1832 MB): VenHw(E61D73B9-A384-4ACC-AEAB-82E828F3628B)/Usb(0x6,0x1)
  net0 90:59:af:5c:d0:94

  default: hd0a

Boot from the network with:

  boot net0:netbsd

The kernel will select the network interface with a mac address matching 
the "net0" mac address above as root device by default. You can override 
this with the root= kernel cmdline option.

These are debug messages from U-Boot. We can probably just comment them 
out of our pkg.
