3# Makefile snippet to ${MDSETIMAGE} file system images into kernels
4#
5
6#
7# Required variables:
8#	_SRC_TOP_	Top level of src tree (set by <bsd.own.mk>)
9#	MDSETTARGETS	List of images to ${MDSETIMAGE} into kernels,
10#			containing one or more tuples of the form:
11#				KERNEL	IMAGE	FILENAME
12#
13#			The kernel is ${MDSETIMAGE} with ${IMAGE},
14#			${STRIP}ped (with the symbols are stored in
15#			${FILENAME}.symbols.gz), and gzipped into
16#			${FILENAME}.gz.
17#
18#			If FILENAME is "-", use "netbsd.${KERNEL}" as
19#			the target name.
20#
21# Optional variables:
22#	MDSETDIR			Where to install release kernels.
23#
24#	MDSET.${FILENAME}.post		For each kernel named ${FILENAME},
25#					execute this after ${NM} / ${STRIP}.
26#					Kernel is available as netbsd.tmp.
27#					If MDSET.${FILENAME}.suffixes uses
28#					this to build extra kernels, the
29#					resultant file must be gzipped as
30#					"netbsd.${suffix}.gz"
31#
32#	MDSET.${FILENAME}.suffixes	List of extra install kernel suffixes.
33#					The extra kernels are usually created
34#					by MDSET.${FILENAME}.post.
35#
36# Variables modified by this:
37#	KERNELS			List of kernel .gz files to build
38#	KERNELDEPS		Dependency version of ${KERNELS} (with .WAIT)
39#	KERNELSYMS		List of kernel .symbol files to build
40#	_KERNEL.${KERNEL}	Target filename for ${KERNEL}
