fastboot_ext4 plugin

fastboot_ext4 image build element

A ScriptElement implementation for creating fastboot ext4sparse images

The fastboot default configuration:

#fastboot ext4sparse image default configuration

# When specifying dependencies, one needs to specify
# which dependencies are a part of the 'input' for
# the image, other dependencies are assumed to be tooling
# required to build the image and will be staged in "/"
#
# E.g.:
#
# build-depends:
# - base.bst
# - filename: input1.bst
#   config:
#     input: True
# - filename: input2.bst
#   config:
#     input: True
#
