It looks strange to have a board related dependency resolution at cpu level. I would rather add the following in boards/esp32s3_wt32_sc01_plus/Kconfig:
select MODULE_ESP_I2C_HW if MODULE_PERIPH_I2C
@MrKevinWeiss, any opinion?

Agreed and I tried it exactly in that way but it threw an error:
=== [ATTENTION] Testing Kconfig dependency modelling ===
[genconfig.py]:ERROR-Treating Kconfig warnings as errors:
[genconfig.py]:ERROR-=> warning: the choice symbol MODULE_ESP_I2C_HW (defined at cpu/esp32/periph/Kconfig.i2c:21) is selected by the following symbols, but select/imply has no effect on choice symbols
- BOARD_ESP32S3_WT32_SC01_PLUS (defined at boards/esp32s3-wt32-sc01-plus/Kconfig:11)

Would it be a possible approach to define a symbol BOARD_REQUIRES_ESP_I2C_HW which selects MODULE_ESP_I2C_HW as default for the ESP32_I2C_IMPLEMENTATION and to set it by that board?

In this case you should actually use a default choice override in the board.
You cannot select choice options directly in kconfig
in boards/esp32s3_wt32_sc01_plus/Kconfig:
choice ESP32_I2C_IMPLEMENTATION
default MODULE_ESP_I2C_HW

Maybe it is time to change the default I2C driver for the ESP32-S3 to the hardware driver, which had some problems on the ESP32 but seems to work fine on the ESP32-S3. It would have to be tested a bit more. |

I haven't tested it though...

Ok, I did it in that way. I squashed it directly. |
