## Summary This PR intends to create a new tree for **Espressif**'s chips based on **RISC-V architecture**. Chips supported under this new tree share a big set of common characteristics, so this approach prevents the usual code duplication and fragmentation between chips. It currently supports the following chip series: - **ESP32-C3** - **ESP32-C6** - **ESP32-H2** For each chip, a generic board description for each chip based on the ESP32-XX-DevKit[C/M] official development kits from Espressif is able to fully boot into NSH with support to: - Clock configuration (**RTC** initialization included) - **UART0** for console - **SYSTIMER** for System Tick - **MWDT0** for Watchdog ## Impact Support for new chips, no side-effect is expected on the currently supported chips or NuttX subsystems. ## Testing `wdog` application successfully executing on the following targets: - `esp32c3-generic:watchdog` on [ESP32-C3-DevKitM-1](https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/hw-reference/esp32c3/user-guide-devkitm-1.html) - `esp32c6-generic:watchdog` on [ESP32-C6-DevKitC-1](https://espressif-docs.readthedocs-hosted.com/projects/espressif-esp-dev-kits/en/latest/esp32c6/esp32-c6-devkitc-1/user_guide.html) - `esp32h2-generic:watchdog` on [ESP32-H2-DevKitM-1](https://www.espressif.com/en/products/devkits#:~:text=Getting%20Started-,ESP32%2DH2%2DDevKitM%2D1,-ESP32%2DH2%2DDevKitM) -- This is an automated message from the Apache Git Service.
