9aa57b6c53 virtio: add virtio framework in NuttX
1. virtio devics/drivers match and probe/remote mechanism;
2. virtio mmio transport layer based on OpenAmp (Compatible with both
   virtio mmio version 1 and 2);
3. virtio-serial driver based on new virtio framework;
4. virtio-rng driver based on new virtio framework;
5. virtio-net driver based on new virtio framework
   (IOB Offload implementation);
6. virtio-blk driver based on new virtio framework;
7. Remove the old virtio mmio framework, the old framework only

4b94dc3092 toolchain/gcc: fix linker error if enable STACK_CANARIES/LTO at same time
If -fstack-protector-all is enabled, gcc linker will need GCC
SSP(Stack Smashing Protector) support, Since the implement of SSP
is related to the OS, most of embedded toolchain does not provide
ssp support, so an error will be reported when linking:

enable CONFIG_LTO_FULL && CONFIG_STACK_CANARIES

arm-none-eabi/bin/ld: cannot find -lssp_nonshared: No such file or directory
arm-none-eabi/bin/ld: cannot find -lssp: No such file or directory

https://github.com/gcc-mirror/gcc/blob/master/gcc/gcc.cc#L983-L985

Since nuttx has already implemented SSP related hook functions,
so in this PR, we filter out this option in the link phase to ensure that
the implementation of lssp/lssp_nonshared will not be referenced

of other cores will be flushed by the contents in the cache of core0,

4ed48c33e9 arm64/a64: Add support for Multiple UART Ports
Currently only Port UART0 is supported for Allwinner A64. This PR adds support for all UART Ports: UART1 to UART4. (Except R-UART, which is a special low-power UART)

This is required for the upcoming LTE Modem Driver (Quectel EG25-G) for PINE64 PinePhone, which uses UART3. [(Details here)](https://lupyuen.github.io/articles/lte2)

The code was adapted from the NuttX UART Driver for Allwinner A1X: [`a1x_serial.c`](https://github.com/apache/nuttx/blob/master/arch/arm/src/a1x/a1x_serial.c)

`arch/arm64/src/a64/a64_serial.c`: Added ports UART1 to UART4, based on [`a1x_serial.c`](https://github.com/apache/nuttx/blob/master/arch/arm/src/a1x/a1x_serial.c)

`arch/arm64/src/a64/a64_serial.h`: Added IRQs for UART1 to UART4. Moved UART Base Addresses to `a64_memorymap.h`

`arch/arm64/src/a64/hardware/a64_memorymap.h`: Added UART Base Addresses for UART0 to UART4

`arch/arm64/src/a64/Kconfig`: Added UART1 to UART4 to Allwinner A64 Peripheral Selection menu

`boards/arm64/a64/pinephone/configs/lcd/defconfig`, `lvgl/defconfig`, `nsh/defconfig`, `sensor/defconfig`: Fixed `UART1_SERIAL_CONSOLE` to `UART0_SERIAL_CONSOLE`

0f243bde33 arch: fix the issue of asynchronous signal processing
in SMP, signal processing cannot be nested, we use xcp.sigdeliver to identify whether there is currently a signal being processed, but this state does not match the actual situation
One possible scenario is that signal processing has already been completed, but an interrupt occurs, resulting in xcp.sigdeliver not being correctly set to NULL,
At this point, a new signal arrives, which can only be placed in the queue and cannot be processed immediately
Our solution is that signal processing and signal complete status are set in the same critical section, which can ensure status synchronization

1 Similar to Linux and zephyr, all implementations are in arm64_arch_timer.c

2 Arm64 tickless is turned off by default. If it needs to be turned on, you need to configure the switch CONFIG_SCHED_TICKLESS ON

3 The implementation strategy for tick/tickless is to use the timer inside the CPU and implement the timer driver based on the ARCH_TIMER framework.

4 We implemented tick_* Callback functions to adapt to the driven interface to avoid time format conversion overhead

5 In arm64_tick_cancel func,The remaining time that is not used, so this value can be ignored without reading the corresponding register to obtain the remaining cycles

6 Currently, tick/tickless can takes effect in SMP and non SMP mode, ostest can pass.

c00498c164 arch/arm: update running task when context switch occurred
The text describes an issue related to the running task in code.
The running task is only used when calling the _assert function
to indicate the task that was running before an exception occurred.
However, the current code only updates the running task during
irq_dispatch, which is suitable for ARM-M architecture but not
for ARM-A or ARM-R architecture, because their context switches
are not done through irq handler. Therefore, if the following
process is followed, the value of the running task will be incorrect:

1. task1 is running, this_task()=task1
2. do_irq is executed, setting running task()=task1
3. task1 switches to task2
4. task2 is running and generates a data abort
5. In the data abort, the _assert function is called,
   and the running task obtained is still task1, but
   the actual task that generated the exception is task2.

Summary

   VMPIDR_EL2 holds the value of the Virtualization Multiprocessor ID.
From architecture manual of AArch64, the behave is:
  -reading register MPIDR_EL1 in EL2, it's return real MPIDR_EL1
  -reading register MPIDR_EL1 in EL1, it's return VMPIDR_EL2
  So since NuttX for SMP is running at EL1 to read MPIDR_EL1 for
  identify CPU id, it's need to set VMPIDR_EL2 to MPIDR_EL1 for
  every CPU at boot EL2 stage.
  For some platform, the bootloader or hypervisor will do that at
  the EL2 stage, but not all.

  This is fixed by making a stack frame to the user stack and copying it
  there.
- If the signal handler uses a system call, the kernel stack was completely
  and unconditionally destroyed, resulting in a crash in the user application

There is also no need to check ustkptr, it is always NULL. Why ? Because
signal delivery is deferred when a system call is being executed.

- The driver for X-Powers AXP803 Power Mgmt IC, which calls our driver for Allwinner A64's Reduced Serial Bus. The PMIC Driver is needed to power on the MIPI DSI Interface for the LCD Panel.

- A simple Display Driver that renders a Test Pattern on the LCD Display at startup. It calls our Allwinner A64 drivers for Display Engine, Timing Controller TCON0 and MIPI Display Serial Interface.

The NuttX Frame Buffer Driver will be implemented in the next PR.

`arch/arm64/src/a64/a64_de.c`, `a64_de.h`: Changed the Frame Buffer pointer to `const` for Allwinner A64 Display Engine

`arch/arm64/src/a64/hardware/a64_memorymap.h`: Added the Base Address for PWM, for controlling the PWM Backlight

`boards/arm64/a64/pinephone/src/pinephone_bringup.c`: Call `fb_register()` to start the Display Driver at startup

`boards/arm64/a64/pinephone/src/Makefile`: Added LCD Driver, PMIC Driver and Display Driver to Makefile
