To enable the root device selection (kernel cmd-line) via PARTUUID, this patch enables CMD_PART on all missing theadorable-x86 boards and changes the default environment to generate the root=PARTUUID string automatically.
This fixes problems that have been noticed on systems with multiple SATA/AHCI controller connected via PCIe, where the device name for the root device / partition (/dev/sdaX) was incorrect.
