2 # Macro that builds the needed Makefile target to create a root
3 # filesystem image.
4 #
5 # The following variable must be defined before calling this macro
6 #
7 #  ROOTFS_$(FSTYPE)_CMD, the command that generates the root
8 #  filesystem image. A single command is allowed. The filename of the
9 #  filesystem image that it must generate is $$@.
10 #
11 # The following variables can optionaly be defined
12 #
13 #  ROOTFS_$(FSTYPE)_DEPENDENCIES, the list of dependencies needed to
14 #  build the root filesystem (usually host tools)
15 #
16 #  ROOTFS_$(FSTYPE)_PRE_GEN_HOOKS, a list of hooks to call before
17 #  generating the filesystem image
18 #
19 #  ROOTFS_$(FSTYPE)_POST_TARGETS, the list of targets that should be
20 #  run after running the main filesystem target. This is useful for
21 #  initramfs, to rebuild the kernel once the initramfs is generated.
22 #
23 # In terms of configuration option, this macro assumes that the
24 # BR2_TARGET_ROOTFS_$(FSTYPE) config option allows to enable/disable
25 # the generation of a filesystem image of a particular type. If
26 # configura options BR2_TARGET_ROOTFS_$(FSTYPE)_GZIP,
27 # BR2_TARGET_ROOTFS_$(FSTYPE)_BZIP2 or
28 # BR2_TARGET_ROOTFS_$(FSTYPE)_LZMA exist and are enabled, then the
29 # macro will automatically generate a compressed filesystem image.
