timer frequency a power of two. This changes the frequency from 10 to
16.7 MHz (2 ^ 24 HZ). Using a power of two avoids roundoff errors when
doing arithmetic in sbintime_t units.
Testing shows this can fix erratic ntpd behavior in guests using the
hpet timer (which is the default for multicore guests).

- Remove FreeBSD 4.x of building the kernel.
While it might technically work, it is better to
document the 'correct' way than how to shoot oneself
in the foot
- Remove reference to CVS -P for src.
Define EFISRC, EFIINC and EFIINCMD. Use them, as well as using other
symbols defined in defs.mk. Prefer <bsd.init.mk> to ../../Makefile.inc
or <src.opts.mk>.

It is possible that building headers requires an OBJDIR.
The other phases of xdev have their own 'make obj' calls
where needed, such as inside 'make libraries' itself.

Having objects in world32 and a sysroot in lib32 was confusing and
inconsistent with the normal build. Now objects are stored in
obj-lib32 (or obj-libsoft) and the sysroot (analagous to WORLDTMP)
is stored in obj-lib32/tmp.

Without this the user has to mess with 'make -f Makefile.inc1 ...' to figure
out where the files are installed in the OBJDIR and then they need to copy them
to where they really wanted them. Using DESTDIR may be problematic after
r325001 as well.
The files will be installed to DESTDIR/NXTP where NXTP defaults to /nxb-bin.

The top of Makefile.inc1 requires TARGET/TARGET_ARCH be defined. Just
building 'make xdev' would already set them, so this error was never
triggered. Moving it to Makefile fixes the problem.

The original change was dealing with the build wanting to run a newer
install(1) that was not yet installed. The solution to look into the private
legacy directory of the existing build conflicts with 2 upcoming features: a
changed OBJDIR format, and splitting the host tools into arch-dependent and
arch-independent directories. Rather than hardcoding and changing the paths in
this script, just let kernel-toolchain do the work, while disabling much of the
meat. With -j15 this finishes in 25 seconds for me and 117 seconds with -j1.
All that is really needed is bootstrap-tools, but the system is not currently
written in a way that all previous dependent steps will have ran. The previous
steps, such as _worldtmp, are being reworked and renamed and so cannot be
relied upon to be right.

Its own build target was already handling mtree extractions
just as _worldtmp did, so the other cleaning of the
tmpdir makes sense here as well.

Only remove them if the option is enabled and also handle libsoft
by using the proper LIBCOMPAT_OBJTREE. LIBCOMPAT:D will expand
the text after it as a proper glob to the command line if LIBCOMPAT

The _worldtmp target is for setting up WORLDTMP. Nothing between _worldtmp
and _cleanobj will read these files. Move to its own target since it is
so large.

This leaks into the PATH handling for WORLDTMP and breaks
finding cross-tools. The PATH handling could be fixed to
properly quote but is not worth the effort.
Also allow this sanity check to always run even with 'make -n'.

The bug is an out-of-bounds read detected with address sanitizer that
happens when 'sp' in p_b_coll_elems() includes NUL byte[s], e.g. if it's
equal to "GS\x00". In that case len will be equal to 4, and the
strncmp(cp->name, sp, len) call will succeed when cp->name is "GS" but the
cp->name[len] == '\0' comparison will cause the read to go out-of-bounds.
Checking the length using strlen() instead eliminates the issue.
The bug was found in LLVM with oss-fuzz:

Obtained from: Vlad Tsyrklevich through posting on openbsd-tech
fields in the softc; they're ORed together in the ofw_compat_data.
I already caught myself doing 'sc->fectype == <enum val>' without masking
out the feature bits in one place, and that's sure to happen again.
Glomming them together is convenient for storing them in the ofw_compat_data
array, but there's no reason to keep them together in the softc.
We don't need to check if casper is present, this is done in the library itself.

When available, enabling this feature causes the hardware to write data
to the receive buffer starting at a 16-bit offset from the start address.
This eliminates the need to copy the data after receiving to re-align
the protocol headers to a 32-bit boundary.

The idea behinds mocks is that we don't need to ifdef a lot of code in
tools itself but those defines are hidden in the casper library.
Right now the mocks are implemented as define/inlines functions.
There was a very long discussion how this should be implemented.
This approach has some advantages like we don't need to link to any additional
libraries. Unfortunately there are also some disadvantages for example it is
easy to get library out of sync between two versions of functions or that we
need extra define to compile program with casper support.
This isn't an ideal solution but it's good enough for now and should simplify
capsicumizing programs. This also doesn't close us any other ways to do those
mocks and this should evolve in time.

Newer hardware splits the interrupts onto 3 different irq lines, but the
docs barely mention that there are multiple interrupts, and do not detail
how they're split up. The code now supports 1-3 irqs, and uses the same
interrupt service routine to handle all of them.
I modified the submitted changes to use bus_alloc_resources() instead of
using loops to allocate each irq separately. Thus, blame any bugs on me (I
can't actually test on imx7 hardware).

When the FEC is connected to the AXI bus (indicated by AVB flag), a
MAC reset while a bus transaction is pending can hang the bus.
Instead of resetting, turn off the ENABLE bit, which allows the
hardware to complete any in-progress transfers (appending a bad CRC
to any partial packet) and release the AXI bus. This could probably
be done unconditionally for all hardware variants, but that hasn't
been tested.

This flag is analogous to the Linux driver FEC_QUIRK_HAS_AVB. It
indicates an FEC with support for Audio Video Bridging (AVB). This
indicator is used for various other parts in the Linux driver
(drivers/net/ethernet/freescale/fec_main.c).
Use it to customize the receive/transmit buffer alignment. The receive
buffer alignment increased to 64-bytes on the i.MX 6SoloX and i.MX
7Dual. There are no hard alignment restrictions for transmit buffers on
these chips.
Fix the ffec_softc::fectype type to provide enough storage for the
feature flags.

16 was the correct alignment for older hardware, but the imx7 requires
64-byte alignment, which is a fine value to use on all systems.
