13-CURRENT on Gigabyte ThunderX system: "pci_host_generic_core_alloc_resource FAIL" and "bgx0: Could not find matching PHY"

[Rebecca Cran]

I recently got a Gigabyte ThunderX system. There are some problems
booting FreeBSD 13-CURRENT (from March) on it. I tried booting with both
kern.cfg.order=acpi and kern.cfg.order=fdt . In ACPI mode I saw
complaints that it couldn't find FDT related data, so I guess that's an
unsupported configuration. With kern.cfg.order unset, I see the
following in dmesg:
