Our design is Harmony based, but unlike the original Harmony board we
have eMMC instead of removable SDMMC card, which means that for now the
only way for us to update the software on the board is to use nvflash.
Nvflash, to the best of my knowledge at least, does not support flashing
of eMMC for boards other than Ventana and Cardhu, and that forces us to
use one of the NAND partitions to store kernel image and rootfs.
