This is a sample GPT partition layout for SD card,
right now three important partitions are added to
make the system bootable.

Right now the board doesn't support the environment,
so the U-Boot environment and ESP partitions will
add in future.

partition layout:

Part    Start LBA       End LBA         Name

        Type GUID
        Partition GUID

        type:   linux
        guid:   99f4fd58-6e52-4a2b-b5f0-035f5756ad01

Note:
- loader1 would be fsbl or spl
- loader2 would be U-Boot or U-Boot proper
