This fixes a problem where u-boot's BAR remapping conflicts with some limitations in bhyve. See =20=20=20 https://lists.freebsd.org/archives/freebsd-virtualization/2024-April/002103= .html for a description of what goes wrong. The old behaviour can be restored by setting the pci.enable_bars configuration variable.
