# Modification from mkefidisk.sh provided by the Yocto project by Dominig
# to install Automotive Grade Linux (AGL) on
# Intel platforms equipped with the Automotive Linux Boot (ABL)
#
# Dependencies:
# Relies on the Intel iasImage tool to pakage the Kernel and the initrd in ABL format
#
# changes
# - simpler use model
# - keep initrd if present
# - does not allocate swap
# - accept .hddimg, wic and wic.xz as sources
