We will soon remove the BSD_CRTBEGIN option (and will use the new CRT
files always) as part of the GCC 4.2.1 removal. Right now BSD_CRTBEGIN
works everywhere but sparc64; add a reference to the PR in case anyone
stumbles across this and is looking for more information.
Previously the mkfs_msdos function (from newfs_msdos) emitted warnings
in the case that an image size is specified and the target is not a
file, or no size is specified and the target is not a character device.
The latter warning (not a character device) doesn't make sense when this
code is used in makefs, regardless of whether an image size is specified
or not.

Previously we checked for only BINUTILS_BOOTSTRAP as a broken option
and suggested installing the binutils package. This was originally done
for arm64 where we used the in-tree Clang with external binutils package.
Add a case to the warning to suggest instead the full xtoolchain package
if we have no in-tree compiler either.

The man page incorrectly described the use of the"len" argument, which
is updated to the number of bytes copied and not reduced by the number
of bytes copied.
This is a content change.
The memory range between VM_MAXUSER_ADDRESS and VM_MIN_KERNEL_ADDRESS is
reserved for devices currently, which are always mapped in TLB1, and
therefore do not exist in the kernel page table. Any page fault in this
range is therefore automatically a fatal fault.
Since TLB_MAXNEST is 3, the insert mask should only be 2 bits. Given that 2
bits counts to 4, and that we already have plenty of space wasted in
padding, make the nest level 4 to match the mask.
Freescale SoCs use a set of IRQs at the high end of the OpenPIC IRQ
list, not counted in the NIRQs of the Feature reporting register. Some
SoCs include a MSI inbound window in the PCIe controller configuration
registers as well, but some don't. Currently, this only handles the
SoCs *with* the MSI window.
There are 256 MSIs per MSI bank (32 per MSI IRQ, 8 IRQs per MSI bank).
The P5020 has 3 banks, yielding up to 768 MSIs; older SoCs have only one
bank.
On the RPi4, some of these IRQs are shared. Start moving toward a mode where
we accept that shared IRQs happen and simply ignore interrupts that are
seemingly for no reason.
I would like to be more verbose here, but my 30-minute assessment of the
current world order is that mapping a resource/rid to an actual IRQ number
(as found in FDT) data is not a simple matter. Determining if more than one
handler is attached to an IRQ is closer to feasible, but it's unclear which
way is the cleaner path. Beyond that, we're only really using it to be
slightly more verbose when something's going wrong, so for now just suppress
and drop a complaint-comment.
This was originally submitted (via freebsd-arm@) by Robert Crowston; the
additional verbosity was dropped by kevans@.

Add some diagnostic output.
This works around the fact that buildworld calls cleandir in libexec
with the wrong MACHINE_ARCH (i386 on amd64) when the OBJ directory is empty.

TVSENSE may not be ready by the time t4_fw_initialize returns and the

This is the multiqueue receive code required for 9000-series chips.
Note that we still only configure a single RX queue for now. Multiqueue
support will require MSI-X configuration and a scheme for managing a
global pool of RX buffers.

For now iwm only ever uses queue 0 and the management queue, but my 9560
raises a software error interrupt during initialization if this flag is
not set. iwlwifi sets it for all 7000- and 8000-series hardware, so we
might as well do it unconditionally.

Match such chips using the device ID. We should really be checking the
subdevice as well, since a smaller number of 9460 and 9560 devices
actually belong to a new series of devices and require different
firmware, but that will require some extra logic in iwm_attach().

Alter bsd.compat.mk to set MACHINE and MACHINE_ARCH when included
directly so MD paths in Makefiles work. In the process centralize
setting them in LIBCOMPATWMAKEENV.
Alter .PATH and CFLAGS settings in work when the Makefile is included.
While here only support LIB32 on supported platforms rather than always
enabling it and requiring users of MK_LIB32 to filter based
TARGET/MACHINE_ARCH.
The net effect of this change is to make Makefile.libcompat only build
compatability libraries.
Changes relative to r354449:
Correct detection of the compiler type when bsd.compat.mk is used
outside Makefile.libcompat. Previously it always matched the clang
case.
Set LDFLAGS including the linker emulation for mips where -m32 seems to
be insufficent.

This is a standard required property for interrupt controllers, and present
on the bcm_lintc nodes for currently supported RPi models. For the RPi4, we
have both bcm_lintc as well as GIC-400, but only one may be active at a
time.
Don't probe bcm_lintc if it's missing the "interrupt-controller" property --
in RPi 4 DTS, the bcm_lintc node is actually missing this along with other
required interrupt properties. Presumably, if the earlier boot stages will
support switching to the legacy interrupt controller (as is suggested
possible by the documentation), the DTS will need to be updated to indicate
the proper interrupt-parent and hopefully also mark this node as an
interrupt-controller instead.
