This commit sets the BLE's interrupt as a IRAM-enabled interrupt,
which enables it to run during a SPI flash operation. This enables
us to create a cache to off-load semaphores and message queues
operations and treat them when the SPI flash operation is finished.
By doing that, we avoid packet losses during a SPI flash operation.
This commit provides an interface to register ISRs that run from
IRAM and keeps track of the non-IRAM interrupts. It enables, for
instance, to avoid disabling all the interrupts during a SPI flash
operation: IRAM-enabled ISRs are, then, able to run during these
operations.
The board-level GPIO support is different from the already existing
button and LEDC support because it enable us to register the GPIO
pins as devices in `/dev/gpioX`. Some applications are able to use
this interface to read and write the GPIO pins.
Documentation was added regarding its usage. Please check
`Documentation/platforms/xtensa/esp32s3/boards/esp32s3-devkit/index.rst`
Provide initial support for audio through the I2S peripheral to the
CS4344 audio codec on ESP32-S3-DevKitC-1 board.
Please check documentation for usage examples.
ESP32-S3 has only one 2.4 GHz ISM band RF module, which is shared
by Bluetooth and Wi-Fi, so Bluetooth can’t receive or transmit data
while Wi-Fi is receiving or transmitting data and vice versa.
Under such circumstances, ESP32-S3 uses the time-division
multiplexing method to receive and transmit packets.
- Added Wi-Fi related symbols to the kernel-space linker;
- Allocate more RAM to the kernel (to be useb by the Wi-Fi driver).
- Create a specific defconfig.
Instead of setting kernel/user space instruction and data ROM as
hard-coded values on linker, set them according to the max size
of the kernel image set by CONFIG_ESP32S3_KERNEL_IMAGE_SIZE. This
is done by making KIROM, UIROM, KDROM and UDROM dependent on the
kernel size value. Also, override CONFIG_NUTTX_USERSPACE config
according to CONFIG_ESP32S3_KERNEL_IMAGE_SIZE by using a custom
PREBUILD definition.

board/esp32s3/common is for common board driver. It should not
include a header file from specific board. so remove include
of esp32s3-devkit.h from some of the common driver source
