	# Currently, it is required that the BIOS region be a multiple of 8KiB.
	# This is required so that the recovery mechanism can find SIGN_CSE
	# region aligned to 4K at the center of BIOS region. Since the
	# descriptor at the beginning uses 4K and BIOS starts at an offset of
	# 4K, a hole of 4K is created towards the end of the flash to compensate
	# for the size requirement of BIOS region.
	# FIT tool thus creates descriptor with following regions:
	# Descriptor --> 0 to 4K
	# BIOS       --> 4K to 0xf7f000
	# Device ext --> 0xf7f000 to 0xfff000
