Subject: [PATCH] GPT: add support for PReP GUID
|
|
|
|
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.
