# This .inc file allows building and deploying multiple sets of kernel + modules
# with different defconfigs
#
# Note that this include will NOT stage anything nor create packages, since that
# is virtually impossible. Userspace should be built against the 'regular' kernel
#
# The intended usecase is for machines that have mutually exclusive drivers due
# to e.g. pinmuxing issues. For example the LogicPD omap-l138 experimenter board
# can have multiple mutually exclusive expansion boards like lcd, ethernet,
# sound, 20x2 character LCD, etc. To be able to easily test all of those you can
# use this .inc
#
# The function get_kernelversion uses generated header files to extract the
# version number. But those files are not available until do_compile, and
# do_compileconfigs is injected before that, hence the version becomes None
# and breaks in several places. Introduce a task do_preparekernel that calls
# "make prepare" in the kernel tree to generate all the necessary files.
