The MAIXDUINO runs fine with the sipeed_maix_bitm_defconfig but a different board id parameter should be passed to kflash.

The bit can also probably be used with the same defconfig as the bitm. The only major difference is the lack of mic, but U-Boot doesn't care about that.
+Sipeed MAIXDUINO sipeed_maix_bitm_defconfig maixduino first
This is currently supported to the same level as the bit (e.g. nothing supported but serial), but in the future there will need to be a separate device tree for this board since the on-board peripherals are different. Until that happens, can you add some kind of note here?
