# Bootloader component
#
# The bootloader is not a real component that gets linked into the project.
# Instead it is an entire standalone project ( in src/) that gets built in
# the upper projects build directory. This Makefile.projbuild provides the
# glue to build the bootloader project from the original project. It
# basically runs Make in the src/ directory but it needs to zero some variables
# the SDK makefile exports first, to not let them interfere.
