From bdc728a849a7047e55014c6f968aa300cc9f57fa Mon Sep 17 00:00:00 2001 From: Daniel Axtens Date: Tue, 31 Mar 2015 16:00:39 +1100 Subject: [PATCH] powerpc: move find_and_init_phbs() to pSeries specific code Previously, find_and_init_phbs() was used in both PowerNV and pSeries setup. However, since RTAS support has been dropped from PowerNV, we can move it into a platform-specific file.
