commit 96aecb542e2b8684a5ddfc280ad6ea50c743b37d Author: Stefano Stabellini <sstabellini@xxxxxxxxxx> AuthorDate: Tue Jul 31 16:27:50 2018 -0700 Commit: Julien Grall <julien.grall@xxxxxxx> CommitDate: Wed Aug 22 16:28:30 2018 +0100 xen/arm: rename acpi_make_chosen_node to make_chosen_node acpi_make_chosen_node is actually generic and can be reused. Rename it to make_chosen_node and make it available to non-ACPI builds.
