8a0fd1a7cd Add support for the Allwinner A83T (sun8iw6p1) SoC.
Clocks, GPIO, UART, SD card / eMMC, USB, watchdog, and ethernet are
supported. Note that the A83T contains two clusters of four Cortex-A7
CPUs, and only CPUs in first cluster are started for now.

Tested on a Sinovoip Banana Pi BPI-M3.

cca48a59de Add a MULTIDELAY option to allow the ARM kernel to have multiple DELAY

however after the timer has been probed it will switch to a more accurate
implementation.

4b68de9c1a Move the Allwinner kernels to use fdt_pinctrl. This will read the pin
configuration from the FDT data, then set the pins into the requested
state. As part of this the gpio controller now reports the correct number
of pins instead of returning the number of bank * 32.

To allow for a future consolidated kernel we add the SOC_ALLWINNER_A10 and
SOC_ALLWINNER_A20 kernel options. These need to be set as appropriate for
the SoC the kernel will boot on.

56ea9c7b08 Add support for RMII in macb, cribbed slightly from the ate
driver. This is taken from the MAC at boot, but can be overridden with
'options AT91_MACB_USE_RMII'.

Switch to macb for HL201 and SAM9G20EK boards. It now works both
places. Also start to sneak up on FDT for the SAM9G20EK board, but
leave disabled due to issues with MMC that haven't been resolved.

686450c898 Import ARM_INTRNG, the "next generation" interrupt architecture for arm
and armv6 architecures.  The primary enhancement over the old design is
support for hierarchical interrupt controllers (such as a gpio driver
which can receive interrupts from a root PIC and act as a PIC itself for
clients interested in handling a change of gpio pin state as an
interrupt).  The new code also provides an infrastructure for mapping
interrupts described in metadata in the form of a "controller reference
plus interrupt number" tuple into the simple "0-n" flat numeric space
understood by rman and the bus resource mechanisms.

Use of the new code is enabled by setting the ARM_INTRNG option, and by
making a few simple changes to the platform's support code.  In addition
each existing PIC driver needs changes to be ready for INTRNG; this commit
contains the changes for the arm/gic driver, which most armv6 SoCs use, but
it does not enable the new code yet on any platform.

This project has been many years in the making, starting as a GSoC project
by Jakub Klama (jceel@) in 2012.  That didn't get committed right away and
the source base evolved out from under it to some degree.  In 2014 I rebased
the diffs to then -current and did some enhancements in the area of mapping
interrupt numbers and storing associated fdt data, then the project went
cold again for a while.  Eventually Svata Kraus took that work in progress
and did another big round of work on it, removing most of the remaining
rough edges.  Finally I took that and made one more pass through it, mostly
disabling the "INTR_SOLO" feature for now, pending further design
discussions on how to most efficiently dispatch a pending interrupt through
more than one layer of PIC.  The current code with the INTR_SOLO feature
disabled uses approximate 100 extra cpu cycles for each cascaded PIC the
interrupt has to be passed to, so what's left to do is about efficiency, not
correct operation.

37143b98d4 Allow to override default kernel virtual address assignment on ARM
Each plaform performs virtual memory split between kernel and user space
and assigns kernel certain amount of memory space. However, is is sometimes
reasonable to change the default values. Such situation may happen on
systems where the demand for kernel buffers is high, many devices occupying
memory etc. This of course comes with the cost of decreasing user space
memory range so shall be used with care. Most embedded systems will not
suffer from this limtation but rather take advantage of this potential
since default behavior is left unchanged.

81d54b79fc Remove the ARM_DEVICE_MULTIPASS option and make its effect be the default.
Multipass device attachment was tested on many arm platforms by users and
only success was reported on the arm@ mailing list.  This is just the
long-delayed followup of making it the default.

Multipass attachment is necessary when using vendor-supplied FDT data,
because our devices may need to be attached in a different order than they
are described in the FDT data.

970775a5d2 Add an arm option, ARM_DEVICE_MULTIPASS, used to opt-in to multi-pass
device attachment on arm platforms.  If this is defined, nexus attaches
early in BUS_PASS_BUS, and other busses and devices attach later, in the
pass number they are set up for.  Without it defined, nexus attaches in
BUS_PASS_DEFAULT and thus so does everything else, which is status quo.

Arm platforms which use FDT data to enumerate devices have been relying
on devices being attached in the exact order they're listed in the dts
source file.  That's one of things currently preventing us from using
vendor-supplied fdt data (because then we don't control the order of the
devices in the data).  Multi-pass attachment can go a long way towards
solving that problem by ensuring things like clock and interrupt drivers
are attached before the more mundane devices that need them.

The long-term goal is to have all arm fdt-based platforms using multipass.
This option is a bridge to that, letting us enable it selectively as
platforms are converted and tested (the alternative being to just throw
a big switch and try to fight fires as they're reported).

007aeeced6 Remove the ARM_USE_SMALL_ALLOC option and code related to it.
This was an optimization used only by a few xscale platforms.  Part of
the optimization was to create a direct map for all physical pages, and
that resulted in making multiple mappings of pages in a way that bypassed
the logic in pmap.c to handle VIVT cache aliasing.  It also just generally
made the code more complex and hard to maintain for all SoCs.

4442f74b81 Port the new PV entry allocator from amd64/i386/mips to armv6/v7.
PV entries are now roughly half the size.
Instead of using a shared UMA zone for 28 byte pv entries
(two 8-byte tailq nodes, a 4 byte pointer, a 4 byte address and 4 byte
flags), we allocate a page at a time per process.
This provides 252 pv entries per process (actually, per pmap address space)
and eliminates one of the 8-byte tailq entries since we now can track
per-process pv entries implicitly.
The pointer to the pmap can be eliminated by doing address arithmetic to
find the metadata on the page headers to find a single pointer shared by
all 252 entries. There is an 8-int bitmap for the freelist of those 252
entries.
When in serious low memory condition, allocation of another pv_chunk is
possible by freeing some pages in pmap_pv_reclaim().

Added pv_entry/pv_chunk related statistics to pmap.
pv_entry/pv_chunk statistics can be accessed via sysctl vm.pmap.

Ported PTE freelist of KVA allocation and maintenance from i386.
Using an idea from Stephan Uphoff, use the empty pte's that correspond
to the unused kva in the pv memory block to thread a freelist through.
This allows us to free pages that used to be used for pv entry chunks
since we can now track holes in the kva memory block.

As both ARM pmap.c and pmap-v6.c use the same header and pv_entry, pmap and
md_page structures are different, it was needed to separate code designed
for ARMv6/7 from the one for other ARMs.
