8b47c1ae54 Rename the ThunderX CPU identification macros to include the X. This is the 
name people know the product by, and is consistent with the later SoC ID
macros.

f94f8e62ab To allow for an ACPI attachment to the generic PCIe driver split off the 
FDT attachment to a new file. A separate ACPI attachment will then be added
to allow arm64 servers with ACPI to use it over FDT.

This should also help with merging this with the ofwpci driver, with
further work needed to remove restrictions this driver places on resource
allocation.

2760c2cad4 Mark the ThunderX and generic PCI drivers as cache-coherent when we know 
this to be the case. This will mean we don't try and handle the cache in
bus_dmamap_sync when it is not needed.

1e43b18c4b Add a pcib interface for use by interrupt controllers that need to 
translate the pci rid to a controller ID. The translation could be based
on the 'msi-map' OFW property, a similar ACPI option, or hard-coded for
hardware lacking the above options.

2445e7c84e Restore ThunderX Pass1.1 PCI changes removed by r295962 
If Enhanced Allocation is not used, we can't allocate any random
    range. All internal devices have hardcoded place where they can
    be located within PCI address space. Fortunately, we can read
    this value from BAR.

fb05500b24 Make pci_host_generic and thunderx_pci common 
* provided OFW interface for pci_host_generic (for handling devices which are present in DTS under the PCI node)
  * removed support for internal PCI from arm64/cavium
  * cleaned up and made most of the code common

7915adb560 Introduce a RMAN_IS_DEFAULT_RANGE() macro, and use it. 
This simplifies checking for default resource range for bus_alloc_resource(),
and improves readability.

This is part of, and related to, the migration of rman_res_t from u_long to
uintmax_t.

db7cfc199e Fix VNIC enumeration after r294993 and r294990 
ofw_bus_get_node() must be tested against negative values since
missing parent bus method will result in calling the default method
which simply returns (-1): sys/dev/ofw/ofw_bus_if.m
This was lost in the review process.

68a594774e Add FDT bus capabilities to ThunderX PCI driver 
New ThunderX firmware incorporates modified DTB that presents
different device hierarchy. In the new device tree, MDIO
devices are below two additional buses that oddly hang on
PCI bridge.

bc5758b633 Divide ThunderX PCIe driver to general and FDT part 
- Separate FDT and general PCIe driver parts
- Drop some irrelevant printfs that cannot be displayed in
  FDT attach
- Move ranges parsing to FDT portion of PCIe code
