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.

Used ttyS0 console.
Removed usage of ttyPCH0 (FRI2 leftover)
Decreased bootloader timeout to 5 seconds
Removed 'vmalloc=256MB snd-hda-intel.enable_msi=0' as it's not needed
for any of reference BSPs.

Stopped using GPT partition table in mkefidisk.wks as it's not
supported by all reference hardware.

This is a preparation to use mkefidisk as a default wks for
genericx86* BSPs. This change enables usage of partition UUID
instead of device name to specify root partition in kernel
command line. It should make images to boot on devices with
boot device names that differ from what's mentioned in wks file.

Moved content of scripts/lib/image/ to scripts/lib/wic as
one directory with the same name as a tool is self-explanatory
and less confusing than two.
