From 7e990266c845d7f712c96013891aaf74baef198f Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Fri, 5 May 2006 00:02:08 -0500 Subject: [PATCH] powerpc: provide ppc_md.panic() for both ppc32 & ppc64 Allow boards to provide a panic callback on ppc32. Moved the code to sets this up into setup-common.c so its shared between ppc32 & ppc64. Also moved do_init_bootmem prototype into setup.h.
