ESP32-SPARROW-KIT is built upon ESP32-WROVER-KIT by adding various
peripherals. This is an initial commits that only backports the code
as it is, without further changes.

In order to turn longjmp context-switch safe, it's necessary
to disable interrupts before modifying windowbase and windowstart.
Otherwise, after a context switch, windowstart and windowbase
would be different, leading to a wrongly set windowstart bit due to
longjmp writing it based on the windowbase before the context switch.
This corrupts the registers at the next window overflow reaching
that wrongly set bit.
*Background:*
This PR is related to an issue first observed on ESP-IDF
https://github.com/espressif/esp-idf/issues/5229 and it was, then,
checked on NuttX using a test application.
*The test application:*
To check if the problem affects ESP32, ESP32-S2 and ESP32-S3 on
NuttX, it was created an application based on:
https://en.cppreference.com/w/c/program/longjmp
The application creates 16 tasks (`#define NUMBER_OF_TASKS 16`)
that implements the following daemon:
```
static int setjmp_longjmp_daemon(int argc, char *argv[])
{
for (int i = 0; i < NUMBER_OF_TASKS * 2; i++)
{
jmp_buf env;
volatile int count = 0;
if (setjmp(env) != UINT16_MAX)
{
foo(&env, ++count);
}
}
sem_post(&g_sem);
return EXIT_SUCCESS;
}
```
The main function also initializes a semaphore to avoid application
exiting before tasks return successfully:
```
sem_init(&g_sem, 0, -NUMBER_OF_TASKS);
```
Finally, the round-robin interval was lowered to 1ms to raise the
chances of the longjmp being interrupted by a context switch
(`CONFIG_RR_INTERVAL=1).
This setup was able to reproduce the problem prior to this patch
being applied.
- Add ioctl method to enable allocating the apb buffer.
- Add RX methods to set data width, sample rate, channels and
for receiving data from the I2S peripheral.
- Update the i2schar defconfig to enable the I2S receiver.
- Add nxlooper defconfig to enable testing the RX interface.
- Add specific bindings on ESP32-S2 bringup to enable nxlooper
to work without the need of any specific codec.
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.
