-# 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

+# 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.
