1* ThunderX PCI host controller for pass-1.x silicon
2
3Firmware-initialized PCI host controller to on-chip devices found on
4some Cavium ThunderX processors.  These devices have ECAM-based config
5access, but the BARs are all at fixed addresses.  We handle the fixed
6addresses by synthesizing Enhanced Allocation (EA) capabilities for
7these devices.

9The properties and their meanings are identical to those described in
10host-generic-pci.txt except as listed below.

12Properties of the host controller node that differ from
13host-generic-pci.txt:
