2024-01-27esp32c3: update linker script to support binary blobsAyke van Laethem
To be able to link with the binary blobs that provide wifi and BLE, the linker script needs a few tweaks.
2024-01-27esp32c3: add more ROM functionsAyke van Laethem
These functions are used by the binary blobs that implement wifi/BLE on the ESP32-C3. While this is a lot of lines of linker script, I think it's a good idea to add them here (instead of in a separate library) because they're part of the ESP32-C3 hardware.

2021-09-16esp32c3: add support for this chipAyke van Laethem
This change adds support for the ESP32-C3, a new chip from Espressif. It is a RISC-V core so porting was comparatively easy. Most peripherals are shared with the (original) ESP32 chip, but with subtle differences. Also, the SVD file I've used gives some peripherals/registers a different name which makes sharing code harder. Eventually, when an official SVD file for the ESP32 is released, I expect that a lot of code can be shared between the two chips.
