+Checking (validating) GPT partitions in U-Boot:
+===============================================
+
+Procedure is the same as above. The only change is at point 3.
+
+At u-boot prompt one needs to write:
+ gpt verify mmc 0 [$partitions]
+
+where [$partitions] is an optional parameter.
+
+When it is not provided, only basic checks based on CRC32 calculation for GPT
+header and PTEs are performed.
+When provided, additionally partition data - name, size and starting
+offset (last two in LBA) - are compared with data defined in '$partitions'
+environment variable.
+
+After running this command, return code is set to 0 if no errors found in
+on non-volatile medium stored GPT.
+
+Following line can be used to assess if GPT verification has succeed:
+
+U-BOOT> gpt verify mmc 0 $partitions
+U-BOOT> if test $? = 0; then echo "GPT OK"; else echo "GPT ERR"; fi
+
+
+Partition type GUID:
+====================
+
+For created partition, the used partition type GUID is
+PARTITION_BASIC_DATA_GUID (EBD0A0A2-B9E5-4433-87C0-68B6B72699C7).
+
+If you define 'CONFIG_PARTITION_TYPE_GUID', a optionnal parameter 'type'
+can specify a other partition type guid:
+
+ "partitions=uuid_disk=...;name=u-boot,size=60MiB,uuid=...;
+ name=kernel,size=60MiB,uuid=...,
+ type=0FC63DAF-8483-4772-8E79-3D69D8477DE4;"
+
+Some strings can be also used at the place of known GUID :
+ "system" = PARTITION_SYSTEM_GUID
+ (C12A7328-F81F-11D2-BA4B-00A0C93EC93B)
+ "mbr" = LEGACY_MBR_PARTITION_GUID
+ (024DEE41-33E7-11D3-9D69-0008C781F39F)
+ "msft" = PARTITION_MSFT_RESERVED_GUID
+ (E3C9E316-0B5C-4DB8-817D-F92DF00215AE)
+ "data" = PARTITION_BASIC_DATA_GUID
+ (EBD0A0A2-B9E5-4433-87C0-68B6B72699C7)
+ "linux" = PARTITION_LINUX_FILE_SYSTEM_DATA_GUID
+ (0FC63DAF-8483-4772-8E79-3D69D8477DE4)
+ "raid" = PARTITION_LINUX_RAID_GUID
+ (A19D880F-05FC-4D3B-A006-743F0F84911E)
+ "swap" = PARTITION_LINUX_SWAP_GUID
+ (0657FD6D-A4AB-43C4-84E5-0933C84B4F4F)
+ "lvm" = PARTITION_LINUX_LVM_GUID
+ (E6D6D379-F507-44C2-A23C-238F2A3DF928)
+
+ "partitions=uuid_disk=...;name=u-boot,size=60MiB,uuid=...;
+ name=kernel,size=60MiB,uuid=...,type=linux;"
+
+They are also used to display the type of partition in "part list" command.
