[coreboot-gerrit] New patch to review for coreboot: 10ed74c Add simple_device_t

21 Jun 2013

Kyösti Mälkki (kyosti.malkki@gmail.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/3508
-gerrit
commit 10ed74c6d50a969f5d82ed8056a9940c1178bef7
Author: Kyösti Mälkki kyosti.malkki@gmail.com
Date:   Thu Jun 20 20:25:21 2013 +0300
Add simple_device_t
Declare the functions that may be used in both romstage and ramstage
    to use simple_device_t instead. This will later allow to define PCI access
    functions for ramstage using the inlined functions from romstage.
