Configuring GPT Devices

GUID Partition Table (GPT) is a standard for the layout of the partition table on a physical hard disk. For general information on GPT, see GUID Partition Table at:

http://en.wikipedia.org/wiki/GUID_Partition_Table

In the kernel configuration file, enable the following partition types:
```
CONFIG_PARTITION_ADVANCED=y
CONFIG_EFI_PARTITION=y
```
In your flash.cfg configuration file, specify the GP1 partition.

Partitions between this partition and GPT are exposed, although only those selected to mount are mounted.

Among other attributes for GP1 partitions, the following attributes must be set as specified here:
```
filesystem_type=basic
type=GP1
```
Specify the GPT partition.

Among other attributes for GPT partitions, the following attributes must be set:
```
filesystem_type=basic
type=GPT
size=0xFFFFFFFFFFFFFFFF
```
Note: The GPT partition must be the last partition.
Specify fill and extension attributes, depending on your platform. For Xavier, set the GPT partition allocation_policy attribute to sequential.
