From 0a498d96a3324c16add35da0435bc7c13b6c6f3f Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Mon, 9 Jan 2006 20:17:01 +1100 Subject: [PATCH] powerpc: set CONFIG_PPC_OF=y always for ARCH=powerpc The CONFIG_PPC_OF symbol is used to mean that the firmware device tree access functions are available. Since we always have a device tree with ARCH=powerpc, make CONFIG_PPC_OF always Y for ARCH=powerpc. This fixes some compile errors reported by Kumar Gala, but in a different way to his patch. This also makes prom_parse.o be compiled only if CONFIG_PPC_OF so that non-OF ARCH=ppc platforms will compile.
