* Update IDF to e931fe9 and add esp-face

* Fix PIO builds fail because of sketch size

* Fix example build failing for Arduino

* Added ESP32 FM DevKit

* Added ESP32 FM DevKit variant

Fixed pin definitions for unused pins.

* Add APB change callbacks and move cpu code to own file

* Properly set esp_timer and FreeRTOS tick dividers

* Improve updated devisors

* No need to update REF_TICK yet

* Add initial handling for UART baud change

* fix uartWriteBuf and uartDetectBaudrate

* trigger callbacks even when APB did not change

* toggle UART ISR on CPU change

* add XTAL freq getter and add cpu freq validation

* Support CPU frequency changes in I2C (#2287)

**esp32-hal-i2c.c**
* add callback for cpu frequency changes
* adjust fifo thresholds based on cpu frequency and i2c bus frequency
* reduce i2c bus frequency if differential is too small
**Wire.h**
* version to 1.1.0

* Implement clock change for the other peripherals

* remove bad CPU clock values from the menu

* Add note to CPU freqs that support WiFi and BT

interfaces

The default SPI bus is VSPI (see libraries/SPI/src/SPI.cpp). This change corrects a misleading comment in a code example which was stating wrongly that HSPI would be the default one.

* Shows only free internal heap on logs

Since Mbedtls is running only on internal heap, show internal + PSRAM available memory on logs can confuse the users

* Clarify logs

* Update IDF to 97eecfa and enable reboot on WDT

* Add API to enable/disable WDT for Core 1 and Arduino Loop

fix copy/paste error

changed LORA_IO0 -> LORA_IRQ
added LORA_RST
added SS

* Add updateBaudRate to hardware serial

* remove flush

* Fix tab

The I2C hardware has limitations on min and max bus frequency directly related to CPU frequency, bus speed cannot be greater than 1/100 CPU clock, nor less than CPU clock / 8192.

* Add support to HAL for APB frequencies different than 80MHz

* Add support for CPU frequencies in the IDE board menu

* Switch to fast set_config

* Add method to uart so debug can be reassigned after apb frequency switch

* Return real APB frequency

Experimental!

This is necessary to avoid this log entry from being generated due to invalid usage of setTimeout:
[E][WiFiClient.cpp:236] setSocketOption(): 1006 : 9

* Add FreeRTOS exsample

* Update Code

* Change stack size

* Fix LED_BUILTIN not defined

Fix LED_BUILTIN not defined

* Replaced ARDUINO_VARIANT with const char

* Fixed missing return value

* Added quotes around defined value in macro (Issue #2193)

closes: https://github.com/espressif/arduino-esp32/pull/2151

Fixes https://github.com/espressif/arduino-esp32/issues/1595

* ESP-IDF da2116f + esp32-camera f8f26ab +BLE b232e7f

* Fix fail compilation due to missing cpp guard

Add MD5 computation to Esp and add request header with MD5 hash of the running sketch to HTTPUpdate (#2176)

* Fix error in PR #2048: if ::available() is called before ::connect() _rxBuffer is not initialised

* Fixed flash size check and added SPIFFS size check

* Rewriting ESP.getFreeSketchSpace(), moving code from HTTPUpdate.cpp
