From 471a9bc14444e79bb826616becd2e5531e591d30 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Wed, 24 Sep 2014 12:36:30 +0200 Subject: sysbus: Expose MMIO enumeration helper Sysbus devices have a range of MMIO regions they expose. The exact number of regions is device specific and internal information to the device model. Expose whether a region exists via a public interface. That way our platform bus enumeration code can dynamically determine how many regions exist.
