The device tree file k210.dts is renamed to k210_generic.dts and becomes the default dwivalue selection of the SOC_KENDRYTE_K210_DTB_BUILTIN_SOURCE configuration option. No device beside the serial console is defined by this device tree. This makes it suitable for all known K210 boards using a builtin initramfs. Most updates to the k210.dtsi file come from Sean Anderson's work on U-Boot support for the Kendryte K210.
