This patch adds the capability for tasks from different
multiconfigs to depend on one another.
These dependencies can be enabled using the following format:
task[mcdepends] = "multiconfig:FROM-MC:TO-MC:PN:task-to-depend-on"
For the sake of simplicity consider the following example:
Assuming we have set up multiconfig builds, one for qemux86 and one for
qemuarm, named x86 and arm respectively.
Adding the following line to an image recipe (core-image-sato):
do_image[mcdepends] = "multiconfig:x86:arm:core-image-minimal:do_rootfs"
Would state that core-image-sato:do_image from x86 will depend on
core-image-minimal:do_rootfs from arm so it can be executed.
This patch makes modifications to:
- cooker: To glue both multiconfigs in one place and make sure
the dependencies can be provided.
- taskdata: To parse and add a new kind of dependency (mcdepends) to
the taskdata object.
- runqueue: To differentiate tasks from different multiconfigs,
add the specified dependencies to the corresponding tasks, and
create a working runqueue that contains tasks from both multiconfigs.
- siggen: To avoid looking for tasks from different multiconfigs on
objects where they dont belong.
The taskdata objects are still not aware of the concept of multiconfig,
so each object doesnt know which multiconfig its building, hence why
the mcdepends are added to all taskdata objects equally (we really
dont expect many of these), but the actual dependencies are added only
to the required tasks by the runqueue.
