'fastboot' images are Android sparse images, which can be loaded onto
development boards using the fastboot protocol, available on many development
boards, as well as a very large number of read devices (phones, tablets, ...).

In this implementation, the 'fastboot' image type relies on standard linux
mkfs.ext4 to generate the file system and uses ext2simg from android-tools to
generate the sparse image. android-tools has its own tool to build an ext4
image, but it usually has less features than the standard linux mkfs.ext4
(especially with regards to file attributes).
