TegraPT is compatible with EFI part but it can't pass Protective MBR check. Skip this check if CONFIG_TEGRA_PARTITION is enabled, storage uclass is MMC and devnum is 0. Note, eMMC on supported devices MUST be aliased to mmc0.
Why wouldn't you use U-Boot's gpt command to fix the non-conformant partition table?

Say Y here if you would like to use U-Boot on a device with
