f7937d11a2 arch: arm64: Fix qemu_pl011_txint() in qemu_serial.c
Summary:
- I noticed that the nsh prompt can not be shown when disabling
  debug features. Actually, the prompt will be shown when a user
  input happens.
- This commit fixes this issue by adding uart_xmitchars() as
  other serial drivers do.

Impact:
- None

Testing:
- Tested with qemu-armv8a:netnsh on QEMU-7.1

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.

e2df52390a SMP: fix crash when switch to new task which is still running
Situation:

Assume we have 2 cpus, and busy run task0.

CPU0                                CPU1
task0 -> task1                      task2 -> task0
1. remove task0 form runninglist
2. take task1 as new tcb
3. add task0 to blocklist
4. clear spinlock
                                    4.1 remove task2 form runninglist
                                    4.2 take task0 as new tcb
                                    4.3 add task2 to blocklist
                                    4.4 use svc ISR swith to task0
                                    4.5 crash

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
