Block Device Emulation
----------------------
U-Boot can use raw disk images for block device emulation. To e.g. list
the contents of the root directory on the second partion of the image
"disk.raw", you can use the following commands:
=>host bind 0 ./disk.raw
=>ls host 0:2
A disk image can be created using the following commands:
$> truncate -s 1200M ./disk.raw
$> echo -e "label: gpt\n,64M,U\n,,L" | /usr/sbin/sfdisk ./disk.raw
$> lodev=`sudo losetup -P -f --show ./disk.raw`
$> sudo mkfs.vfat -n EFI -v ${lodev}p1
$> sudo mkfs.ext4 -L ROOT -v ${lodev}p2
