I want to generate the fsl_clock files (and potentially the feature files) for the i.MX7D M4 for the mcuxpresso sdk. I do not want full board support, I'm just trying to use the ecspi module so that I can create a shim driver in Zephyr for imx spi. Since the mcuxpresso configurator does not support this board, how can I easily generate the clock files? It would be too much work to manually construct it from the freertos bsp. Alternatively, I would like an interface similar to the mcuxpresso sdk escpi interface over the freertos ecspi driver.
