# The loading rules:
# From the 2017.1 release, bistreams should be loaded bfore ATF...
# ...preferably immediately after the FSBL and PMUFW.
#
# While the first few components must be fsbl and pmufw per:
# https://www.xilinx.com/support/documentation/sw_manuals/xilinx2021_2/ug1283-bootgen-user-guide.pdf
#
# This combination restricts the boot order to be:
# FSBL & PMUFW -> Bitstream (if available) -> ATF -> Device Tree (if available) -> Second Stage Bootloader
