This patch has the driver for 10Gigabit Ethernet controller in AMD
SoC. This driver is written compatible to the Iflib framework. The
existing driver is for the old version of hardware. The submitted
driver here is for the recent versions of the hardware where the Ethernet
controller is PCI-E based.

Communicating with the Raspberry Pi firmware is currently handled by each
driver calling into the mbox driver, however the device tree is structured
such that they should be calling into a firmware driver.
Add a driver for this node with an interface to communicate to the firmware
via the mbox interface.
There is a sysctl to get the firmware revision. This is a unix date so can

The ice(4) driver is the driver for the Intel E8xx series Ethernet
controllers; currently with codenames Columbiaville and
Columbia Park.
These new controllers support 100G speeds, as well as introducing
more queues, better virtualization support, and more offload
capabilities. Future work will enable virtual functions (like
in ixl(4)) and the other functionality outlined above.
For full functionality, the kernel should be compiled with
"device ice_ddp" like in the amd64 NOTES file, and/or
ice_ddp_load="YES" should be added to /boot/loader.conf so that
the DDP package file included in this commit can be downloaded
to the adapter. Otherwise, the adapter will fall back to a single
queue mode with limited functionality.
A man page for this driver will be forthcoming.

This reapplies logical r360944 and r360946 (reverting r360955), with fixed
copystr() stand-in replacement macro. Eventually the goal is to convert
consumers and kill the macro, but for a first step it helps if the macro is
correct.
Prior commit message:
Unlike the other copy*() functions, it does not serve to copy from one
address space to another or protect against potential faults. It's just
an older incarnation of the now-more-common strlcpy().
Add a coccinelle script to tools/ which can be used to mechanically
convert existing instances where replacement with strlcpy is trivial.
In the two cases which matched, fuse_vfsops.c and union_vfsops.c, the
code was further refactored manually to simplify.
Replace the declaration of copystr() in systm.h with a small macro
wrapper around strlcpy (with correction from brooks@ -- thanks).
Remove N redundant MI implementations of copystr. For MIPS, this
entailed inlining the assembler copystr into the only consumer,
copyinstr, and making the latter a leaf function.

The arm_physmem interface found in arm's MD code provides a convenient
set of routines for adding/excluding physical memory regions and
initializing important kernel globals such as Maxmem, realmem,
phys_avail[], and dump_avail[]. It is especially convenient for FDT
systems, since we can use FDT parsing functions and pass the result
directly to one of these physmem routines. This interface is already in
use on arm and arm64, and can be used to simplify this early
initialization on RISC-V as well.
This requires only a couple trivial changes:
- Move arm_physmem_kernel_addr to arm/machdep.c. It is unused on arm64,
and manipulated entirely in arm MD code.
- Convert arm32_btop/arm64_btop to atop. This is equivalently defined
on all architectures.
- Drop the "arm" prefix.

Platform (N1SDP).
Neoverse N1 is a high-performance ARM microarchitecture designed
by the ARM Holdings for the server market.
The PCI part on N1SDP was shipped untested and suffers from some
integration issues.
For instance accessing to not existing BDFs causes System Error
(SError) exception. To mitigate this, the firmware scans the bus,
catches SErrors and creates a table with valid BDFs. That allows
us to filter-out accesses to invalid BDFs in this driver.
Also the root complex config space (BDF == 0) has an unusual
location in memory map, so remapping accesses to it is required.
Finally, the config space is restricted to 32-bit accesses only.
This was tested on the ARM boxes kindly provided by the ARM Ltd
to the DARPA CHERI Project.

- memory aperture of his controller is only 16MiB, so it is nearly
unusable for graphic cards
- every attempt to generate type 1 config cycle always causes trap.
These config cycles are disabled now and we don't support cards
with PCIe switch.
- in some cases, attempt to do config cycle to (probably) not-yet ready

Update the NetBSD Kernel Concurrency Sanitizer (KCSAN) runtime to work in

This can be enabled by enabling KCSAN in the kernel config, or by using the
GENERIC-KCSAN amd64 kernel. It works on amd64 and arm64, however the later
needs a compiler change to allow -fsanitize=thread that KCSAN uses.

We could maintain the static conversions for the !AArch64 Raspberry Pis, but
I'm not sure it's worth it -- we'll traverse the platform list exactly once
(of which there are only two for armv7), then every conversion there-after
traverses the memory map listing of which there are at-most two entries for
these boards: sdram and peripheral space.
Detecting this at runtime is necessary for the AArch64 SOC, though, because
of the distinct IO windows being otherwise not discernible just from support
compiled into the kernel. We currently select the correct window based on
/compatible in the FDT.
We also use a similar mechanism to describe the DMA restrictions- the RPi 4
can have up to 4GB of RAM while the DMA controller and mailbox mechanism can
technically, kind of, only access the lowest 1GB. See the comment in
bcm2835_vcbus.h for a fun description/clarification of this.
