zhangyuan21 f8b5fd2a9a arch/arm64: send sgi with correct aff and target list
armv8r and armv8a have different process affinity,
and sgi affinity needs to be able to adapt all of them.

qinwei1 518eb4076e arm64: ARMv8-r(Cortex-R82) support(mpid fix)
Summary
  Different ARM64 Core will use different Affn define, the mpidr_el1
value is not CPU number, So we need to change CPU number to mpid
and vice versa, the patch change the mpid define into platform

Lee Lup Yuen 6aba739f05 arch/arm64: Add support for Generic Interrupt Controller Version 2
Currently NuttX on Arm64 supports Generic Interrupt Controller (GIC) Versions 3 and 4: [`arm64_gicv3.c`](https://github.com/apache/incubator-nuttx/blob/master/arch/arm64/src/common/arm64_gicv3.c), [`arm64_gic.h`](https://github.com/apache/incubator-nuttx/blob/master/arch/arm64/src/common/arm64_gic.h). This PR adds support for GIC Version 2, which is needed by [Pine64 PinePhone](https://lupyuen.github.io/articles/interrupt) based on Allwinner A64 SoC.

This 64-bit implementation of GIC v2 is mostly identical to the existing GIC v2 for 32-bit Armv7-A ([`armv7-a/arm_gicv2.c`](https://github.com/apache/incubator-nuttx/blob/master/arch/arm/src/armv7-a/arm_gicv2.c), [`armv7-a/gic.h`](https://github.com/apache/incubator-nuttx/blob/master/arch/arm/src/armv7-a/gic.h)), with minor modifications to support 64-bit Registers (Interrupt Context).

-   `arch/arm64/Kconfig`: Under "ARM64 Options", we added an integer option `ARM_GIC_VERSION` ("GIC version") that selects the GIC Version. Valid values are 2, 3 and 4, default is 3.

-   `arch/arm64/src/common/arm64_gicv2.c`: Implements 64-bit GIC v2 based on 32-bit [`armv7-a/arm_gicv2.c`](https://github.com/apache/incubator-nuttx/blob/master/arch/arm/src/armv7-a/arm_gicv2.c) and [`armv7-a/gic.h`](https://github.com/apache/incubator-nuttx/blob/master/arch/arm/src/armv7-a/gic.h), modified to support 64-bit Registers (Interrupt Context).

    Function and Macro Names have not been changed, for easier cross-referencing between the 32-bit and 64-bit implementations of GIC v2.

-   `arch/arm64/src/common/arm64_gicv3.c`: Added Conditional Compilation for GIC v3. This file will not be compiled if `ARM_GIC_VERSION` is 2.

-   `arch/arm64/src/common/arm64_gic.h`: Added the Version Identifier for GIC v2. At startup we read the GIC Version from hardware and verify that it matches `ARM_GIC_VERSION`.

-   `arch/arm64/include/qemu/chip.h`: Added the QEMU Base Addresses for GIC v2.

-   `arch/arm64/src/common/Make.defs`: Added the source file that implements GIC v2.

-   `boards/arm64/qemu/qemu-armv8a/README.txt`: Added the documentation for testing GIC v2 with QEMU.

-   `boards/arm64/qemu/qemu-armv8a/configs/nsh_gicv2/defconfig`: Added the Board Configuration `qemu-armv8a:nsh_gicv2` for testing GIC v2 with QEMU. Identical to `qemu-armv8a:nsh`, except that `ARM_GIC_VERSION` is 2.

Hidenori Matsubayashi 06cf41901f arch/arm64: cleanup defconfigs
Use CONFIG_ARCH_CHIP_QEMU instead of CONFIG_ARCH_CHIP_QEMU_A53. This is because these configurations depend on the hardware configuration of qemu (memory map, irq numbers, etc.).

qinwei1 e77b06721b arch: arm64: ARMv8-A support for NuttX
N/A

Summary:

Arm64 support for NuttX, Features supported:

1. Cortex-a53 single core and SMP support: it's can run into nsh shell at
   qemu virt machine.

2. qemu-a53 board configuration support: it's only for evaluate propose

3. FPU support for armv8-a: FPU context switching at NEON/floating-point
  TRAP is supported.

4. psci interface, armv8 cache operation(data cache) and smccc support.

5. fix mass code style issue, thank for @xiaoxiang781216, @hartmannathan @pkarashchenko

Please refer to boards/arm64/qemu/qemu-a53/README.txt for detail

Note:
1. GCC MACOS issue
The GCC 11.2 toolchain for MACOS may get crash while compiling
float operation function, the following link describe the issue
and give analyse at the issue:

https://bugs.linaro.org/show_bug.cgi?id=5825

it's seem GCC give a wrong instruction at certain machine which
without architecture features

the new toolchain is not available still, so just disable the MACOS
cibuild check at present
