[PATCH v2 1/2] ieee1275 : Converting plain numbers to constants in Vec5


From: Avnish Chouhan
Subject: [PATCH v2 1/2] ieee1275 : Converting plain numbers to constants in Vec5
Date: Mon, 27 Mar 2023 12:25:39 +0530

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
3. CMO : Enables the Cooperative Memory Over-commitment Option.
4. MAX_CPU : Defines maximum number of CPUs supported.
