-Subject: [PATCH 1/1] ARM: dts: orange-pi-zero-plus2: use fixed mmc indexes
-
-Driver sunxi-mmc has recently been switched to asynchronous probe.
-As a result, mmc indexes can be shuffled breaking existing setups
-where UUIDs are not used for boot devices. Pin mmc indexes to keep
-running the systems where fixed MMC or eMMC are specified,
-e.g. root=/dev/mmcblk0p2.

Patch that pins mmc indexes was not accepted to mainline kernel. Drop that patch and switch to GPT to use partition labels. For GPT the name of the partition in genimage.cfg is used as the label for that partition. Note that the default GPT partition table location conflicts with the SPL location, so move GPT table after bootloaders.
