# This Makefile is used to build sources that are part of the kernel tree.
# What we want are the various programs used by the kconfig system.  We can't
# just directly call the top-level kernel Makefile, as it doesn't provide
# targets to only build the kconfig system.  It provides targets to build
# the kconfig system *and then configure the kernel*.

# What we do is include the top-level kernel Makefile here, to get all the
# variables and rules it defines, and then add our own targets to just build
# the kconfig system.  You can think of this file as a modified version of the
# top-level kernel Makefile that has "kconfig build only" targets added to it.
# Each of these new targets has the prefix v4l- so it doesn't conflict with
# any targets in the kernel Makefile.

# Like the kernel Makefile, this Makefile should have the cwd be the root
# of the kernel source.

# These should be defined on the command line, to override the kernel Makefile
