[Qemu-devel] [PATCH 04/10] spapr_vio: Introduce a liobn number generating macros |
Date: |
Mon, 23 Feb 2015 19:33:54 +1100 |
This introduces a macro which makes up a LIOBN from fixed prefix and
VIO device address (@reg property).
This is to keep LIOBN macros rendering consistent - the same macro for
PCI has been added by the previous patch.
