From f6225c3a0c1f2ef908244c31b91d62066360ce1d Mon Sep 17 00:00:00 2001 From: David Daney Date: Thu, 8 Oct 2015 12:54:16 -0700 Subject: PCI: generic: Fix address window calculation for non-zero starting bus Make the offset from the beginning of the "reg" property be from the starting bus number, rather than zero. Hoist the invariant size calculation out of the mapping for loop. Update host-generic-pci.txt to clarify the semantics of the "reg" property with respect to non-zero starting bus numbers.
