# We want to grab the bootblock right before it goes into the image and wrap
# it inside a BCT, but ideally we would do that without making special, one
# use modifications to the main ARM Makefile. We do this in two ways. First,
# we copy bootblock.elf to bootblock.raw.elf and allow the %.bin: %.elf
# template rule to turn it into bootblock.raw.bin. This makes sure whatever
# processing is supposed to happen to turn an .elf into a .bin happens.
#
# Second, we add our own rule for creating bootblock.bin from
# bootblock.raw.bin which displaces the template rule. When other rules that
# package up the image pull in bootblock.bin, it will be this wrapped version
# instead of the raw bootblock.
