Modifying this configuration to enable support for the board SD card is not trivial for all users. To help beginners getting started with these boards, 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 new 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. As ext2 does not have journaling, the boot options specify a read-only mount of the file system. Similarly to the smaller nommu_k210_defconfig, this new default configuration disables virtual terminal support to reduce the kernel image size. The default device tree selected is unchanged, specifying the simple "k210_generic" device tree file. The user must change this setting to specify the device tree suitable for the board being used (k210_maix_bit, k210_maix_dock, k210_maix_go, k210_maixduino or k210_kd233).
