From 799d6046d3fb557006e6d7c9767fdb96479b0e0a Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Thu, 10 Nov 2005 13:37:51 +1100 Subject: [PATCH] powerpc: merge code values for identifying platforms This patch merges platform codes. systemcfg->platform is no longer used, systemcfg use in general is deprecated as much as possible (and renamed _systemcfg before it gets completely moved elsewhere in a future patch), _machine is now used on ppc64 along as ppc32. Platform codes aren't gone yet but we are getting a step closer. A bunch of asm code in head[_64].S is also turned into C code.
