The Simple Boot feature for Espressif chips is a method of booting
that doesn't depend on a 2nd stage bootloader. Its not the
intention to replace a 2nd stage bootloader such as MCUboot and
ESP-IDF bootloader, but to have a minimal and straight-forward way
of booting, and also simplify the building.
This commit also removes deprecated code and makes this bootloader
configuration as default for esp32s3 targets and removes the need
for running 'make bootloader' command for it.
Other related fix, but not directly to Simple Boot:
- Instrumentation is required to run from IRAM to support it during
initialization. `is_eco0` function also needs to run from IRAM.
- `rtc.data` section placement was fixed.
- Provide arch-defined interfaces for efuses, in order to decouple
board config level from arch-defined values.

This commit implements the common RMT driver (already available for
the other Espressif's xtensa-based devices) for ESP32.
This allows us to have a proper separation between the lower and
upper-half drivers and use the 'ws2812' example to drive WS2812 RGB
LEDs.
This commit updates the Wi-Fi and the BLE driver of ESP32. Most of
the changes rely on using the common sources and header files for
xtensa-based Espressif's SoCs.
The new Wi-Fi driver supports WPA3-SAE for both Station and SoftAP
mode. BLE's coexistence mode was enhanced according to the latest
libraries.
Please note that other sources required minor changes in order to
be compatible with the common sources.
This driver is used with QEMU, to make it possible
to use networking.
This is not the MAC in ESP32, however, it can be used with QEMU.
The code was shamelessly copied from 31dac92e5f
The board's microphone uses 24-bit i2s and this commit also fixes
the segmentation fault caused by the audio buffer overflow.

By integrating the Espressif`s HAL repository into the current
ESP32-S2 implementation on NuttX, it is possible to call functions
that makes it easier to setup the registers of the ESP32-S2,
enabling the usage of common Espressif drivers.
By integrating the Espressif`s HAL repository into the current
ESP32-S3 implementation on NuttX, it is possible to call functions
that make it easier to set up the registers of the ESP32-S3 and
enables the usage of common Espressif drivers. Please note that
Espressif's HAL repository was already being used for the Wi-Fi
driver. Then, this commit includes other source files to be used
by other drivers other than Wi-Fi and reorganize the build process.
The RMT (Remote Control) character driver allows to use the RMT
peripheral (usually, a one-wire peripheral dedicated to driving
IR remote control) as a character driver.
Please note that this perpiheral depends on the lower-half specific
driver implementation.
Once these messages are thrown during the system's bring-up, it is
advisable them to be output by the syslog considering the file

The SmartFS partition needs to be formatted before being mounted.
Otherwise, it would throw an error message. The error message now
contains a suggestion to format the partition when such an error
is detected.

PHY initialization data (PHY initialization data is used for RF calibration) will be loaded from a partition.

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.
It also makes the code look more similar to the ESP32-S3 SPI flash
implementation by creating a common `esp32_spiflash_init` that is
responsible to create the SPI flash operation tasks. The function
intended to initialize the SPI flash partions was, then, renamed to
`board_spiflash_init`.
During PSRAM initialization and flash operations, the Cache needs to be disabled.
So all data and code for the aforementioned scope is required to be placed in Internal RAM.
After https://github.com/apache/nuttx/pull/11007/ was merged, the
path for some files changed, requiring the linker to be fixed to
make it run from the internal memory once again.

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
