The hypervisor is aware of all system properties. For the guest bios
it's hard and complex to detect all system properties. For that reason,
it would be better if the hypervisor creates acpi tables instead of the
guest. Therefore, the hypervisor has to send the acpi tables to the
guest. At the moment, bhyve just copies the acpi tables into the guest
memory. This approach has some restrictions. You have to keep sure that
the guest doesn't overwrite them accidentally. Additionally, the size of
acpi tables is limited.
Providing a plain copy of all acpi tables by fwcfg isn't possible. Acpi
tables have to point to each other. So, if the guest copies the acpi
tables into memory by it's own, it has to patch the tables. Due to
different layouts for different acpi tables, there's no generic way to
do that. For that reason, qemu created a table loader interface. It
contains commands for the guest for loading specific blobs into guest
memory and patching those blobs.
This commit adds a qemu_loader class which handles the creation of qemu
loader commands. At the moment, the WRITE_POINTER command isn't
implement. It won't be required by bhyve's acpi table generation yet.

Relevant/interesting changes:
* make.1: document seemingly unexplained Error code 6.
o compat.c: CompatDeleteTarget skip .PHONY targets to be
consistent with JobDeleteTarget.
o job.c: fix memory leak in handling sysv :from=to modifiers
o unit tests for .MAKE.META.IGNORE_{FILTER,PATHS,PATTERNS}
o var.c: fix parsing of unevaluated subexpressions with
unbalanced '{}'
o cond.c: reduce complexity of evaluating expressions
This is the historical (and still current) behavior, as well as that of
NetBSD, OpenBSD, illumos and Linux (getdents()/getdents64()).

Summary:
Trivial changes for LinuxKPI to use IfAPI. The 'bsdifp' looks unused,
so removed it instead of converting it to a pointer.

Now the PCI drivers have a common interface to read the IOMMU xref

Add a n attachment to the pci_host_generic driver for the Arm DEN0115
PCI Configuration Space Access Firmware Interface [1]. This can be used
when PCI controllers need to implement quirks in the PCI root bus.
To handle this the firmware implements a SMCCC interface the driver can
use to read and write the configuration register.
This has been tested on a Raspberry Pi 4 booting with EDK2.

A delay after toggling CS is required to avoid anomalies like an extra
junk byte in front of the message. Keeping CS asserted is required to
be able to read a status report after writing a command. (The device
won't return the status if CS was deasserted.)
