It is found on boards equipped with LS1028A SoC.
802.1q VLAN grouping is supported.
An external MDIO device is used for communicating with PHYs.
The driver is built as a module by default, it is not included
in GENERIC kernel config.

The r intc interrupt controller seems to do a lot of things :
- It can handle the NMI interrupt
- It have local interrupts for some device that also can be muxed with GIC
- It can serve as an forwarder for the GIC
It's mostly used for deepsleep/wakeup if I understood correctly and we do not
support this on arm64.
For now just forward everything to the GIC so interrupts works again for device
which now have this interrupts controller set since dts v5.12

Implement support for the NXP LS1028A SoC MDIO controller.
It is attached to the internal PCI root complex.
The controller is used to communicate with PHYs of ports connected
to the internal switch.

ENETC it a gigabit Ethernet controller found on the LS1028A board.
It supports basic VLAN offloads - tag extraction, injection and hardware
filtering. Inband MDIO connectivity is used for link status
monitoring through the miibus interface. Fixed-link mode is also
supported, which allows for operation of internal cpu to switch port.
Since no admin interrupts are present in hardware, link status polling
has to be used.
Due to a hardware bug software reset of the NIC results in a external
abort. Because of that most of the hardware initialization is done
during attach. This also means that in the case of an fatal error full
board reset is required.
The enetc_hw.h header was imporoted from Linux. It is dual licensed.

Some arm64 SoCs have nodes in their fdts that describe devices
connected to the internal PCI bus. One such SoC is Freescale LS1028A.
In order to access information stored in them we need to add ofw bus
support to pci. Pass devinfo request up to our parent, which
is responsible for parsing all the information.
It allows to use ofw interface on PCI devices that support it.
This method is similar to sys/dev/acpica/acpi_pci.c.

Summary:
They're nearly identical, so don't use two copies. Merge the newer
driver into the older one, and move it to a common location.
Add the Semihalf and associated copyrights in addition to mine, since
it's a non-trivial amount of code merged.

The C variant in libkern performs excessive branching to find the
non-zero byte instead of using the bsfq instruction. The same code
patched to use it is still slower than the routine implemented here
as the compiler keeps neglecting to perform certain optimizations
(like using leaq).
On top of that the routine can is a starting point for copyinstr
which operates on words instead of bytes.
Tested with glibc test suite.

The old vendor tree was never fully merged and doing partial merge isn't
supported with git subtree merge so a new one was created.
Switch the build to use the new DTS from sys/contrib/device-tree
This also bump the DTS used to be in sync with Linux 5.9
While here change the way to get the linux version, simply hardcode
the value in sys/dts/freebsd-compatible.dts and use awk to get that
to put it in the CFLAGS.
As a bonus we now have the bindings docs available
in sys/contrib/device-tree/Bindings/ so no need to link to the Linux repo
or to the vendor tree.

Hardware overview is provided in the header of smmu.c file.
The support is disabled by default. To enable add 'options IOMMU' to your
kernel configuration file.
The support was developed on Arm Neoverse N1 System Development Platform

Currently, PCI-based devices and ACPI platforms are supported only.
The support was tested on IOMMU-enabled Marvell SATA controller,
Realtek Ethernet controller and a TI xHCI USB controller with a low to
medium load only.
Many thanks to Konstantin Belousov for help forming the generic IOMMU
framework that is vital for this project; to Andrew Turner for adding
IOMMU support to MSI interrupt code; to Mark Johnston for help with SMMU
page management; to John Baldwin for explaining various IOMMU bits.
