This is Atmel/Microchip's official library for interfacing to the Atmel ATECC508 chip. The submodule points to their repository in GitHub. Additionally, this includes the HAL necessary to use this library in esp_open_rtos using the i2c library in extras/i2c. I have also included a tool I wrote to play with the chip as an example under examples/atcatool. The extras module currently overrides atca_iface.h to fix bug in cryptoauthlib (c11-only feature, which breaks c++ builds that want to use cryptoauthlib)
