Denis Carikli (GNUtoo@no-log.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/3142 -gerrit commit cc8e3d343ca774d0f74c672a8429ebb77502d868 Author: Denis 'GNUtoo' Carikli <GNUtoo@no-log.org> Date: Fri Apr 26 12:21:41 2013 +0200 Lenovo ThinkPad X60: Init CBMEM early for CBMEM console support. Enable `EARLY_CBMEM_INIT` for CBMEM console support by looking how other boards do this. This commit is tested by enabling the CBMEM console (`CONSOLE_CBMEM` in Kconfig) and then in GRUB 2 (as a payload) with the cbmemc command from the cbmemc module and in userspace with ./cbmem -c. Both worked.
