Subject: [PATCH] sparc64: Add blocklist GPT support for SPARC
|
|
|
|
Add block-list GPT support for SPARC. The OBP "load" and "boot" methods
|
|
are partition aware and neither command can see the partition table. Also
|
|
neither command can address the entire physical disk. When the install
|
|
happens, grub generates the block-list entries based on the beginning of the
|
|
physical disk, not the beginning of the partition. This patch fixes the
|
|
block-list entries so they match what OBP expects during boot for a GPT disk.
|
|
|
|
T5 and above now supports GPT as well as VTOC.
|
|
|
|
This patch has been tested on T5-2 and newer SPARC systems.
