f4df324224 Add SMP support for the Allwinner A31 and A31s. This updated the existing
code for the A20 to use the new PLATFORM_SMP interface, and extends it to
add support for the new SoCs allowing for both to coexist within the same
kernel.

7133fe0f33 Almost all copies of platform_mp_init_secondary just called
intr_pic_init_secondary. Replace them with a direct call. On BCM2836
and ARMADA XP we need to add this function, but it can be empty.

3210b87554 Remove platform_mp_probe as it's almost identical on most ARM SoCs, and
slightly wrong on the others. We should just check if mp_ncpus is set to
more than one CPU as we may wish to run on a single core even when SMP is
available.

7758916f44 Move ARM_L2_PIPT option to std.armv6 for all armv6 platforms.
Only L2 PIPT cache is supported for __ARM_ARCH >= 6.

In fact, this is just a pure proclamation as this option is used
only in armv4 specific files now.

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.

907fe11655 Update of the Allwinner drivers to:
* Use the Linux compat string
 * Use EARLY_DRIVER_MODULE to attach at the right time
 * Add a generic A10 kernel config file
 * A20 now use generic_timer
 * Add two new dts files for Olimex boards
 * Update our custom DTS file for A10 and A20 to use the same compatible
   property names as the vendor ones.

2b3ad18853 [intrng] Migrate the intrng code from sys/arm/arm to sys/kern/subr_intr.c.
The ci20 port (by kan@) is going to reuse almost all of the intrng code
since the SoC in question looks suspiciously like someone took an ARM
SoC design and replaced the ARM core with a MIPS core.

* migrate out the code;
* rename ARM_ -> INTR_;
* rename arm_ -> intr_;
* move the interrupt flush routine from intr.c / intrng.c into
  arm/machdep_intr.c - removing the code duplication and removing
  the ARM specific bits from here.

Thanks to the Star Wars: The Force Awakens premiere line for allowing
me a couple hours of quiet time to finish the universe builds.

Tested:

* make universe

TODO:

* The structure definitions in subr_intr.c still includes machine/intr.h
  which requires one duplicates all of the intrng definitions in
  the platform code (which kan has done, and I think we don't have to.)

  Instead I should break out the generic things (function declarations,
  common intr structures, etc) into a separate header.

* Kan has requested I make the PIC based IPI stuff optional.

7ce00ee7b4 Rename arm_init_secondary_ic() -> arm_pic_init_secondary(). The latter is
the name the function will have when the new ARM_INTRNG code is integrated,
and doing this rename first will make it easier to toggle the new interrupt
handling code on/off with a config option for debugging.

It also override the if_dwc defaults to set the alternate descriptor type

and the functionality it provided into arm/exception.S.  Rename the main
irq handling routine from arm_handler_execute() to arm_irq_handler() to
make it more congruent with how other exception handlers are named, and
also update its signature to reflect what has long been reality: it is
passed just a trapframe pointer, no interrupt number argument.

add35ed5b8 Follow r261352 by updating all drivers which are children of simplebus
to check the status property in their probe routines.

Simplebus used to only instantiate its children whose status="okay"
but that was improper behavior, fixed in r261352.  Now that it doesn't
check anymore and probes all its children; the children all have to
do the check because really only the children know how to properly
interpret their status property strings.

Right now all existing drivers only understand "okay" versus something-
that's-not-okay, so they all use the new ofw_bus_status_okay() helper.
