Modifying this configuration to enable support for the board SD card is not trivial for all users. To help beginners getting started with this board, add the nommu_k210_sdcard_defconfig default configuration file to set all configuration options necessary to use the board mmc-spi sd card for the root file system. This configuration adds support for the block layer, the mmc-spi driver and modifies the boot options to specify the rootfs device as mmcblk0p1 (first partition of the sd card block device). The ext2 file system is selected by default to encourage its use as that results in only about 4KB added to the kernel image size. The default device tree compiled in is unchanged and must be replaced by the user with the device tree suitable for the board being used (k210_maix_bit, k210_maix_dock, k210_maix_go, k210_maixduino or k210_kd233).
