Great that you got it working. I'd still suggest that CONFIG_MMCBLKDEV_ROOTARG=y be used for new projects with new kernels an with the same aliases hardcoded in barebox and Linux. PARTUUID might be the best thing you can on x86 without an initramfs, but we have device tree, so why not make use of that to be absolutely sure bootloader and Linux address the same partition.
