The logic for creating most of the filesystem images requires a certain number of host packages to be built. However, those packages are not currently listed in the global PACKAGES variables, and they are not dependencies of any other package listed in the PACKAGES variable. While it does not have any practical implications, it makes sense to have those packages listed in the global PACKAGES variable, which this commit implements.

# Macro that builds the needed Makefile target to create a root
|
|
# filesystem image.
|
|
#
|
|
# The following variable must be defined before calling this macro
|
|
#
|
|
# ROOTFS_$(FSTYPE)_CMD, the command that generates the root
|
|
# filesystem image. A single command is allowed. The filename of the
|
|
# filesystem image that it must generate is $$@.
|
|
#
|
|
# The following variables can optionaly be defined
|
|
#
|
|
# ROOTFS_$(FSTYPE)_DEPENDENCIES, the list of dependencies needed to
|
|
# build the root filesystem (usually host tools)
|
|
#
|
|
# ROOTFS_$(FSTYPE)_PRE_GEN_HOOKS, a list of hooks to call before
|
|
# generating the filesystem image
|
|
#
|
|
# ROOTFS_$(FSTYPE)_POST_TARGETS, the list of targets that should be
|
|
# run after running the main filesystem target. This is useful for
|
|
# initramfs, to rebuild the kernel once the initramfs is generated.
|
|
#
|
|
# In terms of configuration option, this macro assumes that the
|
|
# BR2_TARGET_ROOTFS_$(FSTYPE) config option allows to enable/disable
|
|
# the generation of a filesystem image of a particular type. If
|
|
# configura options BR2_TARGET_ROOTFS_$(FSTYPE)_GZIP,
|
|
# BR2_TARGET_ROOTFS_$(FSTYPE)_BZIP2 or
|
|
# BR2_TARGET_ROOTFS_$(FSTYPE)_LZMA exist and are enabled, then the
|
|
# macro will automatically generate a compressed filesystem image.
