From ed7a964786fc50b13410dbd074e9404514e8700f Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Sat, 25 Sep 2010 22:53:44 +0000 Subject: Implement libpayload support and improve life for DOS based flashrom, too Corresponding to flashrom svn r1181. Change the physmap* behaviour to use (void*)-1 as error code instead of NULL. That way, 1:1 mapped memory can be supported properly because (void*)0 is not a magic pointer anymore. (void*)-1 on the other hand is a rather unlikely memory offset, so that should be safe.
