# This top-level kbuild makefile builds all the Linux kernel modules in the
# DDK. To run kbuild, this makefile is copied to $(TARGET_OUT)/kbuild/Makefile
# and make is invoked in $(TARGET_OUT)/kbuild.
# This makefile doesn't define any kbuild special variables apart from
# ccflags-y and obj-m. The variables for objects are picked up by including
# the kbuild makefile fragments named in $(INTERNAL_KBUILD_MAKEFILES). The
# list of objects that these fragments make is collected in
# $(INTERNAL_KBUILD_OBJECTS) and $(INTERNAL_EXTRA_KBUILD_OBJECTS). These
# variables are set according to the build's $(KERNEL_COMPONENTS) and
# $(EXTRA_PVRSRVKM_COMPONENTS). To add a new kernel module to the build, edit
# these variables in the per-build Makefile.
