From 76da19df5b8e186d269f29190696bd31fb6c836b Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Thu, 16 Oct 2008 21:52:08 -0500 Subject: Added arch_lmb_reserve to allow arch specific memory regions protection Each architecture has different ways of determine what regions of memory might not be valid to get overwritten when we boot. This provides a hook to allow them to reserve any regions they care about. Currently only ppc, m68k and sparc need/use this.
