PReP (PowerPC Reference Platform) boot partition is the first partition used in
PowerPC platform for containing the bootable kernel or bootloader. The firmware
searches for this partition and jumps to it for booting. So far no GUID was
specified for this partition type and hence booting from GPT disk was not
supported on this platform. A new GUID 9e1a2d38-c612-4316-aa26-8b49521e5a8b for
PReP partition is proposed to be included in GPT.
