From 88e0d59315f4863537a94f12ef48348764f4316b Mon Sep 17 00:00:00 2001 From: Liviu Dudau Date: Tue, 22 Nov 2016 11:19:18 +0000 Subject: [PATCH 1/1] vexpress64: Juno: Change PCI buss addresses for IO to start from zero. Juno uses a 1:1 mapping between CPU and PCI addresses for IO. First, that will trip devices that cannot use more than 16 bits of addresses for IO, second it is un-necessary as the system can handle zero-based PCI addresses just fine. Change the mapping to start IO bus addresses from zero.
