Judging by the docs the stm32g4 has no i2c support in libopencm3. But I need it. Time permitting I'll put it in in the next few weeks.

I would like to contribute a feature to enable people **to run code from memory rather than flash**.
I believe this feature already exist in STM32CubeIDE when "debugging from RAM".
