Roger Pau Monné baa006f342 xen: introduce a per-arch scratch mapping ranges ... The current approach is to create foreign mappings in any unpopulated address on the memory map. This however can cause issues, as late-loaded drivers could then found their MMIO region has been stolen to be used as foreign mapping scratch space (due to the Xen drivers having started first). Add a local resource manager to the xenpv bus driver, architectures can add suitable resources to that resource manager at boot in order to be used in preference of the generic MMIO resource allocator. No functional change, as the introduced scratch mapping range is not yet populated.
