[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.
