The ARM Makefile was copied from x86 and then modified, and as a result it was carrying a lot of baggage. On top of that, the extra complication made it inflexible, and we need a lot of flexiblity in order to support the fact that the Tegra124 starts on an ARMv4 coprocessor instead of one of the ARMv7 main CPUs.

# 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.
