commit 15a0578ca4b02c8daf8d36c94e5955cfc5885424 Author: Anthony PERARD <anthony.perard@xxxxxxxxxx> AuthorDate: Thu Apr 7 17:58:44 2022 +0200 Commit: Jan Beulich <jbeulich@xxxxxxxx> CommitDate: Thu Apr 7 17:58:44 2022 +0200 build: shuffle main Makefile Reorganize a bit the Makefile ahead of patch "build: adding out-of-tree support to the xen build" We are going to want to calculate all the $(*srctree) and $(*objtree) once, when we can calculate them. This can happen within the "$(root-make-done)" guard, in an out-of-tree build scenario, so move those variable there. $(XEN_ROOT) is going to depends on the value of $(abs_srctree) so needs to move as well. "Kbuild.include" also depends on $(srctree). Next, "Config.mk" depends on $(XEN_ROOT) and $(TARGET_*ARCH) depends on "Config.mk" so those needs to move as well. This should only be code movement without functional changes.
