7167e16b49 Remove sys/mips/rmi. It's been unmaintained since 2011. This hardware
is now unobtanium. It's only had API changes in the last 7 years, and
is responsible for a very large number of them. In addition, there's a
lot of code that reimplements base FreeBSD functionality, diminishing
the chances it still works. Without hardware to teset it on, or
prospects of obtaining such hardware and without vendor support, it's
time to move on.

c3dbef68d5 Remove support for IDT. Only the RouterBoard RB533 used this chip, and
it's at least 5 years out of production. I couldn't find a used one on
ebay and other secondary markets just now, nor when I tried 4 years
ago. It dates from the initial project/mips2 merge 8 years ago, and
hasn't been updated since.

ada611f6ad Retire old ADM 5120 port. It never grew much beyond the original port.
It came into the tree with the project/mips merge 8 years ago. At the
time, it was hard to find a board with enough RAM to run. Now FreeBSD
requires at least 2x the RAM it did then. No changes have happened to
this port apart from API churn and license tagging since then. It ran
OK at the time it was committed, but no sightings in the wild have
happened since shortly after it was committed.

https://www.linux-mips.org/wiki/Adm5120_devices lists a bunch of
boards that were available 5 years ago (but are no longer
available). The beefiest one had only 64MB of RAM which is too
small. The Mirktik RB1xx never had more than 32MB.

Also remove confusing QEMU config file that never ever worked in QEMU
for mips. MALTA is used for that. Another of my past mistakes, false
starts that never amounted to anything.

5daa7f27c5 Remove sys/mips/alchemy. It was still-born when I committed it and it
never got better. It never worked on real hardware and is still mostly
stubs after 8 years when I added it. It has had no real update in that
time apart from API churn. It was added just so it didn't get lost in
the project/mips merge, but maybe it should have been lost as nothing
has come of it. It is time to give up the ghost on this one.

b6f4732cb3 Add a validbcd() routine that uses the bcd2bin_data[] array and returns a
bool indicating whether the input value represents a valid BCD byte.

The existing bcd2bin() routine will KASSERT if asked to convert a bad value,
but sometimes the kernel has to handle BCD data from untrusted sources, so
this will provide a mechanism to validate data before attempting conversion.

This would be have easier/cleaner if the bcd2bin_data[] array contained an
out-of-range value (such as 0xff) in the infill locations that aren't valid,
but it's a global symbol that might be referenced by out-of-tree code
relying on the current scheme, so I'm leaving that alone.

07bd38576d aw_sid: Add support for a64
Newer Allwinner SoCs have nearly identical SID controllers with efuse space
starting at 0x200 into their register space and thermal data available at
0x234, making all of these fairly trivial additions.

The h3 will be added at a later time after some testing, due to a silicon
bug that causes the rootkey (at least) to be read incorrectly unless first
read via the control register.

7000c58871 The variable "minslptime" is pointless and always has been, ever since its
introduction in r83366.  (At that time, this code appeared in vm/vm_glue.c,
because vm/vm_swapout.c did not exist.)  When the FOREACH_THREAD loop
completes, we know that the sleep time for every thread is above whichever
threshold is being applied.

0337438d5d Wrap includes in sys/tslog.h with #ifdef TSLOG.
This is necessary because some non-kernel code #defines _KERNEL and then
includes kernel headers; as a result, it was getting conflicting versions
of curthread and curproc.  Non-kernel code should probably refrain from
defining _KERNEL, but for now hiding these indirect inclusions fixes the
build.

Introduce new set of loader tunables kern.vt.color.N.rgb, where N is a
number from 0 to 15. The value is either comma-separated list decimal
numbers ranging from 0 to 255 that represent values of red, green, and
blue components respectively (i.e. "128,128,128") or 6-digit hex triplet
commonly used to represent colors in HTML or xterm settings (i.e. #808080)

Each tunable overrides one of the 16 hardcoded palette codes and can be set
in loader.conf(5)

e93e5bb0fa Allow use of .WAIT in the LOCAL_DIRS and LOCAL_LIB_DIRS lists.
A comment in Makefile.inc1 has long stated that LOCAL_DIRS are built last,
after the base system.  Incremental improvements in parallel building over
the years have led to LOCAL_DIRS being built in parallel with base system
directories.  This change allows the .WAIT directive to appear in LOCAL_DIRS
and LOCAL_LIB_DIRS lists to give the user some control over parallel
building of local additions.

8b8a7c43a9 Instrument "boot holds" for the benefit of the TSLOG framework. These
are places where the "main thread" of the booting kernel (either the
thread which later becomes swapper or the thread which later becomes
init) has to stop and wait for action to take place in another thread
before continuing.

There are currently three such holds:
1. The intr_config_hooks SYSINIT waits for hooks registered via the
config_intrhook_establish function; this allows (typically) devices
which need interrupts enabled to complete their initialization to do
so before root is mounted.

2. The g_waitidle function waits for the GEOM event queue to be empty;
this ensures that all of the disks which have been attached have been
tasted before we attempt to mount root.

3. The vfs_mountroot_wait function (in addition to calling g_waitidle)
waits for holds registered via root_mount_hold; among other things, this
is used by the USB subsystem to ensure that we don't fail to mount root
if it's located on a USB disk which takes a while to probe.

31a55efdc5 Use the TSLOG framework to record entry/exit timestamps for hammer_time.
The entry must be logged "manually" using TSRAW rather than TSENTER
since PCPU data structures have not yet been initialized and thus
curthread cannot be accessed; &thread0 is what will become curthread
later in hammer_time.

Other MD initialization code should be similarly instrumented in order
to gain visibility into the time spent before entering mi_startup; this
will require some care and testing from people with access to such
hardware.

ae3d6bfa20 Connect kern_tslog.c to the build and add TSLOG / TSLOGSIZE kernel options.
These are intended for debugging purposes and should not be added to
"generic" kernel configurations since they result in a nontrivial amount
of memory being set aside for this purpose, can break if kernel modules are
unloaded, and can potentially leak a dangerous amount of information about
timestamps used as a source of kernel entropy.

e31e71991a Code for recording timestamps of events, especially function entries/exits.
This is a very primitive system, intended for use in measuring performance
during the early system boot, before more sophisticated tools like DTrace
or infrastructure like kernel memory allocation and mutexes are available.

Because this code records pointers to strings rather than copying strings
(in order to keep the memory usage more manageable), if a kernel module is
unloaded after logging an event, Bad Things can happen.  Users are advised
to not do that.

Since cycle counts from the early kernel boot are used as an initial entropy
source, publishing this information to userland could result in inadequate
entropy being kept private to the kernel RNG.  Users are advised to not
enable this on systems with untrusted users.

24888292cd stand/fdt: Make fdt_overlay_apply signature-compatible with libfdt
libfdt will assume a writable fdt overlay blob has been passed in, so make
ours compatible to allow easier review when we try to drop libfdt into
place. overlay from the calling context is writable, making it safe to
simply rip out everything related to copying the overlay blob in
fdt_overlay_apply.

I note here that we still have problems: fdt_overlay_apply, both our version
and libfdt's, may fail and have already clobbered the base fdt to some
extent. Future work will make sure we don't apply a potentially bogus fdt,
instead discarding the base fdt if we had an error.
