+# 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.
