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.

fb853e4270 Push the logic to talk with the MSI/MSI-X interrupt controller to the FDT

52ea10af69 Improve ThunderX PEM driver to work on pass2 revision
Things changed:
    * do not allocate 4GB of SLI space, because it's the waste of
      system resources. Allocate only small portions when needed.
    * provide own implementation of activate_resource which performs
      address translation between PCI bus and host PA address space.
      This is temporary solution, should be replaced by bus_map_resource
      once implemented.

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.

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.

2dd1bdf183 Convert rman to use rman_res_t instead of u_long
Summary:
Migrate to using the semi-opaque type rman_res_t to specify rman resources.  For
now, this is still compatible with u_long.

This is step one in migrating rman to use uintmax_t for resources instead of
u_long.

Going forward, this could feasibly be used to specify architecture-specific
definitions of resource ranges, rather than baking a specific integer type into
the API.

This change has been broken out to facilitate MFC'ing drivers back to 10 without
breaking ABI.
