This commentary was carried over from the x86 version of the same code,
but has actually been inaccurate for a while now. As of FreeBSD 12.x,
all environments are used unless they disable each other. See
39d44f7f15 ("kern_environment: use any provided environments [...]")
for details.

Failure to map RSDP, XSLT and checksum failures are events that can't
happen unless something has gone wrong. As such, they should be reported
always, and not in bootverbose. This has been this way since it was
originally brought in to parse APIC tables.

arm64 requires ACPI RSDP Revision 2.0 since it requires 64-bit physical
addresses. It is an error worth reporting if we have a RSDP pointer, but
it points to the wrong version.

Add the ability to map named components from IORT to their
SMMU or ITS node in order to setup interrupts.
It is now possible to find a node by its name (substring) and
resource ID similar to PCI nodes.
This is needed by work on a driver for NXP's Second Generation
Data Path Acceleration Architecture (DPAA2).

The underlying types for both are the same so arguably this doesn't
really matter, but using the wrong type is still confusing and
technically incorrect.
According to the ARM Design Document "IO Remapping Table Platform"
(DEN 0049D), the "Number of IDs" field of the ID mapping format means
"The number of IDs in the range minus one".

When mapping MSI/MSI-X interrupts throught he Arm IORT ACPI tables we may
need to ignore an interrupt controller even if it is within the bounds the
entry describes. When the SMMUv3 is not using GSIV (non-MSI/MSI-X)
interrupts we need to read the defined field. The Performance Monitoring
Counter Group always ignores the first table entry.

Add new file arm64/acpica/acpi_iort.c to support the "IO Remapping
Table" (IORT). The table is specified in ARM document "ARM DEN 0049D"
titled "IO Remapping Table Platform Design Document". The IORT table
has information on the associations between PCI root complexes, SMMU
blocks and GIC ITS blocks in the system.
The changes are to parse and save the information in the IORT table.
The API to use this information is added to sys/dev/acpica/acpivar.h.
The acpi_iort.c also has code to check the GIC ITS nodes seen in the
IORT table with corresponding entries in MADT table (for validity)
and with entries in SRAT table (for proximity information).

use fdt or acpi.
The GICv2 (interrupt controller) and Generic Timer drivers have been
updated to handle both cases.
As this is early code we still need FDT to find the kernel console, and
some parts are still missing, including PCI support.
