r327106 introduced kobj to syscon so it can be subclassed and fit in with
the rest of the syscon framework. The diff for syscon.c was misapplied in a
clean tree prior to commit, so bring it back to what was included in the
review and tested. The entire file has basically been rewritten from what
was present prior to the kobj work.

This should help reduce confusion between syscon/syscons a little bit.
syscon is a resource generally modeled by FDT platforms, and not to be
confused with syscons.
Allow more flexibility by kobj'ifying syscon and splitting out fdt specific
bits in preparation of a move to the extres framework.
The generic fdt driver has been moved to syscon_generic.c and the fdt
requirement has been removed from the syscon interface, as is common to the
extres framework.

While the BSD-2-Clause license is there, the GPLv2 is also present.
I am unsure of the implications of having both licenses as they are here.
I'll just leave it untagged and open for interpretation.
This allows one to specify, for example, that if there's an igb card
in bus 12, slot 0, function 0, it should be assigned igb5. If there
isn't, or there's one in a different slot, normal numbering rules
apply (hinted units are skipped). Adding 'hint.igb.5.at="pci12:0:0"'
or 'hint.igb.5.at="pci0:12:0:0"' to /boot/device.hints will accomplish
this. The double quotes are important.
The kernel only accepts the strings (in shell notation):
pci$d:$b:$s:$f
and pci$b:$s:$f
where $d is the pci domain, $b is the pci bus number, $s is the slot
number and $f is the function number. A string compare is done with
the current device to avoid another string parser in the kernel. All
numbers are unsigned decimal without leading zeros.

MD_READONLY flag for the md device automatically instantiated during
kernel init for an mdroot filesystem.
Note that there is specifically and by design no tunable or sysctl
control over this feature. Without this option, you already have control
over whether the mdroot fs is writeable using vfs.root.mountfrom.options
from loader(8), the root_rw_mount rcvar, and by using "mount -u[rw] /"
or equivelent on the fly. This option is being added to provide a way
to make the mdroot fs truly immutable before userland code begins running.

The IA32 memory model guarantees that all writes are seen in the program
order. Also, any access to the uncacheable memory flushes the store
buffers. As the consequence, SFENCE instruction is (almost) never needed,
in particular, it is not needed to ensure the correct order of updates as
seen by a PCIe device.
Use atomic_thread_fence_rel() instead of wb() to only emit compiler barriers
on x86 there. Other architectures get the right barrier instruction as
well.

By the ACPI standard (ACPI 5 chapter 8.4 Declaring Processors) Processors
can be implemented in 2 distinct ways:
* Through a Processor object type (which provides P_BLK)
* Through a Device object type
Prior to this change, the FreeBSD driver only supported the former. AMD
Epyc / Poweredge systems we are testing both implement the latter only. Add
the missing support.
Because P_BLK is not defined in the device object case, C-states entering
must be completely controlled via _CST methods rather than P_LVL2/3.
John Baldwin points out that ACPI 6.0 formally deprecates the Processor
keyword, so eventually processors will only be enumerated as Device objects.

bug that requires 'hands off' for a period of time (2.3s) before we
check the RDY bit. Sicne this is a very odd quirk for a very limited
selection of drives, do this as a quirk. This prevented a successful
reset of the card when the card wedged.
Also, make sure that we comply with the advice from section 3.1.5 of
the 1.3 spec says that transitioning CC.EN from 0 to 1 when CSTS.RDY
is 1 or transitioning CC.EN from 1 to 0 when CSTS.RDY is 0 "has
undefined results". Short circuit when EN == RDY == desired state.
Finally, fail the reset if the disable fails. This will lead to a
failed device, which is what we want. (note: nda device needs
work for coping with a failed device).

Currently, N-PHY support in bwn(4) is GPL licensed, and is not included by

during startup. When a brand new chip leaves the factory, it is in a
special power-saving mode that disables most functions on the chip to
save battery power. The chip is stuck in this mode until the first write
to the time registers, which automatically clears the special power-saving
mode and starts the oscillator.
Also, the day-of-week register in this chip counts 1-7, not 0-6, so write
the values accordingly.
These changes are based on the patch submitted by Brian Scott, but I
elimated warnings since this condition is expected, and added some comments,
and so in general blame me for any mistakes.
