RISC-V page table entries support A (accessed) and D (dirty) bits. The
spec makes hardware support for these bits optional. Implementations that
do not manage these bits in hardware raise page faults for accesses to a
valid page without A set and writes to a writable page without D set.
Check for these types of faults when handling a page fault and fixup the
PTE without calling vm_fault if they occur.

After long consultations with re@, core members and mmacy, revert
these changes. Followup changes will be made to mark them as
deprecated and prent a message about where to find the up-to-date
driver. Followup commits will be made to make this clear in the
installer. Followup commits to reduce POLA in ways we're still
exploring.
It's anticipated that after the freeze, this will be removed in
13-current (with the residual of the drm2 code copied to
sys/arm/dev/drm2 for the TEGRA port's use w/o the intel or
radeon drivers).
Due to the impending freeze, there was no formal core vote for
this. I've been talking to different core members all day, as well as
Matt Macey and Glen Barber. Nobody is completely happy, all are
grudgingly going along with this. Work is in progress to mitigate
the negative effects as much as possible.

- In configurations with a pseudo devices section, move 'device crypto'
into that section.
- Use a consistent comment. Note that other things common in kernel
configs such as GELI also require 'device crypto', not just IPSEC.

As discussed in arm@. This is a scaled back version of the prior
commit because xscale is overlaoded in places to mean armv5 or
similar. The OLD XSCALE stuff hasn't been useful in a while. The
original committer (cognet@) was the only one that had boards for
it. He's blessed this removal. Newer XSCALE (GUMSTIX) is for hardware
that's quite old. After discussion on arm@, it was clear there was no
support for keeping it.

Add std.ralink to define common things across all ralink configs.
Add cpu, machine and options INTRNG to this file.
Remove RT1310.hints file reference: that file isn't in our tree.
This port hasn't been updated since it was committed, apart from
housekeeping. There's no known users, and the known hardware for
this port is too thin to run FreeBSD/arm these days well.
This also removes the last armv4 port. We've had no reports of armv4
systems working since FreeBSD 8. All the kernel support for armv4 has
not been removed since it's too intertwined with armv5 support (which
remains in the tree).
RelNotes: Yes
No objection from: arm@
The last known robust version of this code base was FreeBSD 8.2. There
are no users of this on current, and all users of it have abandoned
this platform or are in legacy mode with a prior version of FreeBSD.
All known users on arm@ approved this removal, and there were no
objections.

In the armv4/5 world device statements in these files were common, but in
the v6/7 world, other socs don't put device statements into those files, so
this just brings imx5 and imx6 into line with the current conventions.
It was introduced to the tree in r169320 and r169321 in May 2007.
It never got much use and never became a kernel default. The code
duplicates the default path quite a bit, with slight modifications. Just
yank out the cruft. Whatever goals were being aimed for can probably be met
within the existing framework, without a flag day option.
Mostly mechanical change: 'unifdef -m -UINTR_FILTER'.

On Raspberry Pi platform GPIO controller also responsible for pins

lot of pinmux info is hardcoded. This patch:
- Implements pinctl methods in bcm2835_gpio
- Converts all devices with ad-hoc pinmux info to proper pin control
mechanisms and adds pinmux info in FreeBSD's custom dts files.
- Adds fdt_pinctrl option to RPI2 and RPI-B kernels

Spliting armv5 and armv7 machdep is necessary for adding Armada38X and
ArmadaXP to GENERIC config.
PLATFORM framework checks SOC type in FDT and will select proper
initialization function implementation during runtime.
Pointers to SoC specific implementation are stored in array of
platform_method_t and provided to framework by FDT_PLATFORM_DEF macro.
PLATFORM framework supports also reset function. To simplify implementation
cpu_reset is moved from mv_common to armv5 and armv7 machdep.

DTB Overlays are useful to change/add nodes to a dtb without the need to

Add support for building dtbo during buildkernel.
The goal of DTBO present in the FreeBSD source tree is to fill a gap in
time when we submit changes upstream (Linux). Instead of waiting 2 to 4 months
we can add a DTBO in tree in the meantime.
This is not for adding DTBO for capes/hat/addon boards, those will be
better to put in a ports.
This is also not for enabling a i2c/spi/pwm controller on certain pins,
each user have a different use case for those (which pins to use etc ...)
and we cannot have all possible configuration.

This adds sys/modules/imx with a SUBDIR makefile to make the whole
collection of modules that are specific to these SoCs. Initially, that
"whole collection" consists of the if_ffec and imx_i2c drivers.
The if_ffec driver is referenced in its existing home in ../ffec rather
than moving it into the imx directory, because it's used by powerpc too,
but it is no longer built for all armv6/7 systems.
The imx_i2c driver is newly added as a module.
