108117cc22 [ofw] fix errneous checks for OF_finddevice(9) return value
OF_finddevices returns ((phandle_t)-1) in case of failure. Some code
in existing drivers checked return value to be equal to 0 or
less/equal to 0 which is also wrong because phandle_t is unsigned
type. Most of these checks were for negative cases that were never
triggered so trhere was no impact on functionality.

use it directly.

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.

243b36c321 Remove platform_ipi_send, it's an unneeded as all implementations are
identical.

a89156f53f ARM: Use new ARMv6 naming conventions for cache and TLB functions
in all but ARMv4 specific files.
Expand ARMv6 compatibility stubs in cpu-v4.h. Use physical address
in L2 cache functions if ARM_L2_PIPT is defined.

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.

562246dff8 Add necessary changes to support various Amlogic SoC devices
specially aml8726-m6 and aml8726-m8b SoC based devices.
aml8726-m6 SoC exist in devices such as Visson ATV-102.
Hardkernel ODROID-C1 board has aml8726-m8b SoC.

The following support is included:
  Basic machdep code
  SMP
  Interrupt controller
  Clock control driver (aka gate)

  Real time clock
  UART
  GPIO
  I2C
  SD controller
  SDXC controller
