Now that BCM283x source are buildable with SMP option it cam be moved to
GENERIC SMP config. SMP itself does not work on RPi3 yet due to lack of
PSCI monitor which is work in progress at the moment
Policy for FreeBSD/arm64 kernel config is the same one as for x86
architectures: provide GENERIC kernel bootable on as many systems
as possible. Since there is no SMP support for RPi 3 yet new kernel
config was introduced: GENERIC-UP, which is effectively GENERIC with
SMP option disabled
- Rename SOC_BCM2837 to SOC_BRCM_BCM2837, put it to opt_soc.h
- do not use files.XXX files, just move required sources to
conf/files.arm64 and make them depend on soc_brcm_bcm2837

RPI3 kernel config builds kernel compatible with latest upstream device
tree and firmware: https://github.com/raspberrypi/firmware/tree/master/boot
As of today it's 597c662a613df1144a6bc43e5f4505d83bd748ca
Default console is PL01x, so pi3-disable-bt dt overlay should be configured
in config.txt and stock U-Boot should be patched to use proper serial port.
Yet unsupported: SMP, VCHIQ, RNG driver. RNG requires some work due to
upstream device tree incompatibility.

to add actions that run when a TCP frame is sent or received on a TCP
session in the ESTABLISHED state. In the base tree, this functionality is
only used for the h_ertt module, which is used by the cc_cdg, cc_chd, cc_hd,
and cc_vegas congestion control modules.
Presently, we incur overhead to check for hooks each time a TCP frame is
sent or received on an ESTABLISHED TCP session.
This change adds a new compile-time option (TCP_HHOOK) to determine whether
to include the hhook(9) framework for TCP. To retain backwards
compatibility, I added the TCP_HHOOK option to every configuration file that
already defined "options INET". (Therefore, this patch introduces no
functional change. In order to see a functional difference, you need to
compile a custom kernel without the TCP_HHOOK option.) This change will
allow users to easily exclude this functionality from their kernel, should
they wish to do so.
Note that any users who use a custom kernel configuration and use one of the
congestion control modules listed above will need to add the TCP_HHOOK
option to their kernel configuration.

PCI-express HotPlug support is implemented via bits in the slot
registers of the PCI-express capability of the downstream port along
with an interrupt that triggers when bits in the slot status register
change.
This is implemented for FreeBSD by adding HotPlug support to the
PCI-PCI bridge driver which attaches to the virtual PCI-PCI bridges
representing downstream ports on HotPlug slots. The PCI-PCI bridge
driver registers an interrupt handler to receive HotPlug events. It
also uses the slot registers to determine the current HotPlug state
and drive an internal HotPlug state machine. For simplicty of
implementation, the PCI-PCI bridge device detaches and deletes the
child PCI device when a card is removed from a slot and creates and
attaches a PCI child device when a card is inserted into the slot.
The PCI-PCI bridge driver provides a bus_child_present which claims
that child devices are present on HotPlug-capable slots only when a
card is inserted. Rather than requiring a timeout in the RC for
config accesses to not-present children, the pcib_read/write_config
methods fail all requests when a card is not present (or not yet
ready).
These changes include support for various optional HotPlug
capabilities such as a power controller, mechanical latch,
electro-mechanical interlock, indicators, and an attention button.
It also includes support for devices which require waiting for
command completion events before initiating a subsequent HotPlug
command. However, it has only been tested on ExpressCard systems
which support surprise removal and have none of these optional
capabilities.
PCI-express HotPlug support is conditional on the PCI_HP option
which is enabled by default on arm64, x86, and powerpc.

This is only the minimum set of files needed to boot in qemu. As such it is
missing a few things.
The bus_dma code is currently only stub functions with a full implementation
from the development tree to follow.
The gic driver has been copied as the interrupt framework is different. It
is expected the two drivers will be merged by the arm intrng project,
however this will need to be imported into the tree and support for arm64
would need to be added.
This includes code developed by myself, SemiHalf, Ed Maste, and Robin
Randhawa from ARM. This has been funded by the FreeBSD Foundation, with
early development by myself in my spare time with assistance from Robin.
