From 7fb5aa049bee3c685835dc24c8184c5897e4a6bd Mon Sep 17 00:00:00 2001 From: Stefan Tauner Date: Wed, 14 Aug 2013 15:48:44 +0000 Subject: Automatically unmap physmap()s Similarly to the previous PCI self-clean up patch this one allows to get rid of a huge number of programmer shutdown functions and makes introducing bugs harder. It adds a new function rphysmap() that takes care of unmapping at shutdown. Callers are changed where it makes sense. Corresponding to flashrom svn r1714.
