Subject: [PATCH] ieee1275 : Converting plain numbers to constants in Vec5
|
|
|
|
This patch converts the plain numbers used in Vec5 properties to
|
|
constants.
|
|
|
|
1. LPAR : Client program supports logical partitioning and
|
|
associated hcall()s.
|
|
2. SPLPAR : Client program supports the Shared
|
|
Processor LPAR Option.
|
|
3. CMO : Enables the Cooperative Memory Over-commitment Option.
|
|
4. MAX_CPU : Defines maximum number of CPUs supported.
|
|
