# Modification from mkefidisk.sh provided by the Yocto project by Dominig 
# to install Automotive Grade Linux (AGL) on Minnowboard and any PC with UEFI boot
#
# changes
#         - simpler use model
#         - keep initrd if present
#         - create a grub config with PARTUID to ease boot from various devices automaticaly
#         - add a UEFI startup.nsh script for autoboot
#         - does not allocate swap
#
