I don't think all of them are critical for > booting the system up to a rootfs. Can you please switch over any non-critical > drivers to =m? Okay, let's check them one by one. - CONFIG_SPI_IMX=y @Fabio, do you have a critical use case for this to be 'y'? Or can we change this to 'm'? - CONFIG_RTC_DRV_SNVS=y @Abel, I guess this can be 'm'? Or you have a good reason for this to be 'y'? - CONFIG_PINCTRL_IMX8MM=y, CONFIG_CLK_IMX8MM=y @Olof, I think we shouldn't have problem to have pinctrl and clock driver to be 'y', as they are pretty fundamental for a platform support. - CONFIG_GPIO_MAX732X=y @Olof, this is essentially a GPIO controller, just like CONFIG_GPIO_PCA953X=y currently sitting in defconfig. - CONFIG_I2C_IMX_LPI2C=y @Olof, this is a driver for I2C bus controller which is used for many I2C devices, and above GPIO expander is one example. So we would treat it as fundamental one. - CONFIG_MFD_ROHM_BD718XX=y, CONFIG_REGULATOR_BD718XX=y @Leonard, are they critical for booting imx8mm-evk board up? Or can they be installed as module after system is up? - CONFIG_NVMEM_IMX_OCOTP=y @Olof, this is the driver for fuse access on i.MX platform. Drivers like cpufreq will need to access fuse for cpu grade data. So we would take this driver as fundamental infrastructural.
