They are all broadly similar, all being based on the ESP32-D0WD core, but have
some subtle differences between variants around PSRAM inclusion and camera pin
mappings.
The ESP32CAM "unit" product (SKU: U007) has no PSRAM and maps the
"Pixel Data 0" (Y2 GPIO/OV2640 D2) camera pin to IO17 rather than IO32 as is
the case with most other M5Stack ESP32 camera devices.
The ESP32CAM also requires the "hmirror" and "vflip" camera configuration
bits setting in order to capture a true image.
The relevant M5Stack pin configuration documentation can be found here:

* Add 'KITS Edu ESP32' board definition
add 'KITS Edu ESP32' board definition
* Modify board name
the board name was modified.
* Change the board name
Finally, we decided the board name.
- 'KITS ESP32 EDU'

According to ESP-IDF API
dc14d027ce/docs/en/api-reference/peripherals/sdmmc_host.rst :
"To configure the bus width, set the width field of :cpp:class:`sdmmc_slot_config_t`. For example, to set 1-line mode:
sdmmc_slot_config_t slot = SDMMC_SLOT_CONFIG_DEFAULT();
slot.width = 1;

1. WiFiProv.ino sketch is added that allows arduino users to do provisioning via SoftAP or BLE. WiFi.beginProvision( ) API is designed for provisioning in Arduino.
2. In WiFiProv.h provisioning class is defined.
3. WiFiProv.cpp contains implementation for provisioning class.
4. README.md file is added which contains detail information for working.
The boundary delimiter (_STREAM_BOUNDARY) needs to be send before the
body part (_STREAM_PART) too follow RFC2046. This caused ffplay/ffmpeg
to fail to open the MJPEG stream.
* std::shared_ptr Memory Leak
clientSocketHande and _rxBuffer are std::shared_ptr, the stop() call was not correctly releasing them and the operator= had similar problems fix for #3679
* operator= second attempt
* operator= third time
* Minimize HardwareSerial Receive and Transmit delays
* Remove uartRxFifoToQueue from esp-hal-uart.h

* fix removeApbChangeCallback() error in spiStopBus()
spiStartBus() was using spiStopBus() to init the hardware, one of spiStopBus() functions is to unregister the runtime CPU clock speed change callback. But, spiStartBus() only wanted to init the hardware. This patch separates the hardware init into a standalone function spiInitBus() that both spiStartBus() and spiStopBus() call.
* Update esp32-hal-spi.c
capitalization problem
WiFiClient.connected() was hanging thinking there was still a connection when the remote had already closed. The one-liner in this patch addresses recv() returning 0 and errno==128. I couldn't find the corresponding errno for 128 but its caught by the case statement which includes EPIPE, ENOTCONN, ECONNRESET and ECONNABORTED so I assume its one of those. Broken pipe maybe?
```c
[D][WiFiClient.cpp:511] connected(): Disconnected: RES: 0, ERR: 128
```
EDIT: added comment to reflect that recv() can set errno when it returns 0.
* Fix flush
flush should not flush the read buffer, it should wait till all output is drained from the write buffer.
* Update BluetoothSerial.cpp

fixed the connected() function so that it only checks errno if recv returns a value of -1.
"in the even of an error, errno is set to indicate the error" --manpage
This fixes the ESP32 Webserver when dealing with a modern webserver with a slow SD card.
* API compatibility to AVR, ESP8266, et al
* Add non-blocking HardwareSerial::read(buffer, size) extension (ESP8266 portability)
* Refactor for fewer indirect calls.
