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 Attributes Type GUID Partition GUID 1 0x00000800 0x00000fff "loader1" attrs: 0x0000000000000000 type: 5b193300-fc78-40cd-8002-e86c45580b47 guid: 3b86e786-4b78-4bb2-92ac-7c7b45e73d33 2 0x00001000 0x00002fff "loader2" attrs: 0x0000000000000000 type: 2e54b353-1271-4842-806f-e436d6af6985 guid: c09e2067-3c33-4ceb-993a-fbdc29a6a8cf 3 0x00003000 0x03b9ffde "system" attrs: 0x0000000000000004 type: 0fc63daf-8483-4772-8e79-3d69d8477de4 type: linux guid: 99f4fd58-6e52-4a2b-b5f0-035f5756ad01

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