Most of the functions used to describe the SoCs capabilities are
available for all Espressif's chips. This commit uses this set of
common functions and remove outdated functions that perform the
same operations in a chip level.
1. pm configuration demonstrates the use of power management present on the ESP32-S3.
2. You can use the pmconfig command to test the power management, for details look at

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 just rearranges the order of the types, data and
functions without modifying them. This is done to make it look more
similar with ESP32's ble adapter and ease maintanence.
Most of the functions used to set the peripherals are available for
all Espressif's chips. This commit uses this set of functions and
remove outdated functions that perform the same operations in a
chip level.
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.
Whenever a SPI flash operation will take place, it's necessary to
disable the cache and run no code from the flash. This includes
pausing the other CPU (when `CONFIG_SMP=y`). This commit prevents
an error to occur when the CPU core is evaluated before the task
is increased to the max priority.

Avoid using static mutex and recursive mutex as the resource to be
acquired/release. Instead, create a specific lock for each call if
it does not exist.

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.

ERROR !!!
Reason:
As descript above, cpu0 swith task: thread0 -> thread1, and the
syscall() execute slowly, this time cpu1 pick thread0 to run at
up_cpu_paused(). Then cpu0 syscall execute, cpu1 IRQ leave error.
Resolve:
Move arm64_restorestate() after enter_critical_section() done

WS2812 data is encoded into RMT items according to the RMT clock
source. This commit makes it by using the actual clock source in
spite of a pre-defind value.
Enable with ./tools/configure.sh -l esp32-devkitc:dac
DAC channel 0 = GPIO 25
DAC channel 1 = GPIO 26
default path: /dev/dac0
Resolution 8 bits = values 0~255
Voltage: 0~Vref
The reference voltage 'Vref' here is input from the pin VDD3P3_RTC
which ideally equals to the power supply VDD (3.3V).

ESP32 is supported on NuttX starting from chip revision 3.0. This,
however, didn't prevent the user from using older chip revisions,
which caused unexpected behaviors. This commit checks chip revision
before finishing booting NuttX.
This commit is intended to update the EFUSE's register content and
update related configs:
- Remove duplicated configs from `esp32_soc.h`;
- Add missing header files from APB registers;
- Add missing macro definitions from EFUSE;
- Update related code to use the new macros;
Newly added logging in `sched/task_exit.c` obsoletes the existing
ones in `arch/up_exit()`, thus remove the latter to reduce duplications.

The RT-Timer thread may call the `start_rt_timer` function. This
function gets the spinlock with interrupts disabled to ensure
exclusive access. However, this was already being performed in the
RT-Timer thread, causing a deadlock.
Following up the 'Espressif HAL fullly integration for ESP32s2/s3'
changes in https://github.com/apache/nuttx/pull/11428
There are few missing interrupt type constants need update. So
update them to avoid the build error.
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.
This lower-half WS2812 LED driver uses the RMT peripheral of the
Espressif's SoCs to drive the RGB addressable LEDs. Compared to
the SPI-based implementation, it is faster!
The lower-half implementation of the RMT character driver based on
Espressif HAL enables using the RMT peripheral of ESP32, ESP32-S2
and ESP32-S3 as a common xtensa-based Espressif driver.
The RMT packages on Espressif SoCs are 4-byte long and are known as
"items". Please check the Techinal Reference Manual of the chip to
obtain more details.
1. Solve wifi may not work bug for bbpll not lock or not stable when enable RF.
2. Improved timing tuning stability on ESP32-S3.
The root cause of the issue:
The application won't re-calibrate the BBPLL clock if it's already enabled.
We add a force-recalib function in the app startup code to make sure even if
the patch is applied by OTA, the clock is still re-calibrated.

The `xxx_ipv6multicast` function in each driver is not adapted to
multiple IPv6 addresses yet, and they're redundant, so try to take them
into common code.
Change:
1. Add MAC `g_ipv6_ethallnodes` and `g_ipv6_ethallrouters` in
`icmpv6_devinit` and call them in `netdev_register`
2. Add multicast MAC for Neighbor Solicitation when adding any IPv6
address, and remove them when IPv6 address is removed
3. Select `NET_MCASTGROUP` when `NET_ICMPv6` because now we need
`d_addmac` when we have ICMPv6
Note:
We want modules outside net stack to call functions like
`netdev_ipv6_add` and never touch the related MAC address, so these MAC
functions are added as internal functions to `net/netdev/netdev.h`

Add registration function instrumentation API,
which can achieve instrumentation of entering and
exiting functions through the compiler's functionality.
We can use CONFIG_ARCH_INSTRUMENT_ALL to add instrumentation for all
source, or add '-finstrument-functions' to CFLAGS for Part of the
source.
Notice:
1. use CONFIG_ARCH_INSTRUMENT_ALL must mark _start or entry noinstrument_function,
becuase bss not set.
2. Make sure your callbacks are not instrumented recursively.
use instrument_register to register entry function and exit function.
They will be called by the instrumented function
