* ThunderX PCI host controller for pass-1.x silicon
Firmware-initialized PCI host controller to on-chip devices found on
some Cavium ThunderX processors. These devices have ECAM-based config
access, but the BARs are all at fixed addresses. We handle the fixed
addresses by synthesizing Enhanced Allocation (EA) capabilities for
these devices.
The properties and their meanings are identical to those described in
host-generic-pci.txt except as listed below.
