canned-wks: use GPT partition table
According to UEFI specification all EFI platforms must support
GUID Partition Table(GPT) disk layout. Here is a list of advantages
of using GPT disk layout over the legacy MBR partitioning:
- Logical Block Addresses (LBAs) are 64 bits (rather than 32 bits).
- Supports many partitions (rather than just four primary partitions).
- Provides both a primary and backup partition table for redundancy.
- Uses version number and size fields for future expansion.
- Uses CRC32 fields for improved data integrity.
- Defines a GUID for uniquely identifying each partition.
- Uses a GUID and attributes to define partition content type.
- Each partition contains a 36 character human readable name.
Used GPT partitioning in all EFI kickstart files.
Tested result images on NUC, MinnowBoard MAX and MinnowBoard Turbot.
