Patch set updated for coreboot: 635060e Lenovo X201 support (mobo part)
by Vladimir Serbinenko 23 Nov '13

23 Nov '13

Vladimir Serbinenko (phcoder(a)gmail.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/3462 -gerrit commit 635060e16215f1aab960e3f3538c3d6a6e137e9b Author: Vladimir Serbinenko <phcoder(a)gmail.com> Date: Thu Nov 14 19:11:19 2013 +0100 Lenovo X201 support (mobo part) Lenovo X201 is a recent laptop by lenovo based on nehalem chipset and representing good value for both geeks and less-geeks alike. This commit allows to run it without factory BIOS. Was extensively tested on my X201. Issues - S3 doesn't work - No expresscard hotplug - Sometimes Gnome starts to think that battery is 10 time larger than real Information from sysfs remains correct. - On my X201 there due to recent hardware failure thermal management doesn't work with either coreboot or original BIOS. Before this hardware fault happened thermal management worked under coreboot as well. Requires descriptor.bin (bytes 0-0x2fff from original ROM) and me.bin (bytes 0x3000-0x500000 from original ROM) in 3rdparty/mainboard/lenovo/x201.

ME firmware is not readable. +Rewriteable region can be rewritten easily with flashrom. + +For coreboot we need to preserve descriptor and ME firmware while overwriting +rewriteable region and bootblock. To achieve this there are 2 ways: + +- External flasher. +- Unlock bootblock + +For the first one proceeds as follows: +- Turn off your laptop, remove battery and AC adapter. +- Remove the keyboard. +- Connect your external SPI flasher to the SPI chip which is under keyboard, + around the position of trackpoint under protective layer. I recommend using + SOIC clip. Depending on the flasher you use, you may have to use separate + 3.3V source. Make sure not to feed more than 3.3V ot the chip.

Marc Jones (marc.jones(a)se-eng.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/4018 -gerrit commit 16835a000c59d3b3c7fb78e0001f9db711ec26ad Author: Marc Jones <marc.jones(a)se-eng.com> Date: Tue Oct 29 22:13:38 2013 -0600 intel/cougar_canyon2: Intel CRB FSP based mainboard Cougar Canyon 2 is a Ivybridge/PantherPoint reference board. This implementation uses the Intel FSP (Vist the Intel FSP website for details on FSP architecture and support). The FSP does not support s3 at this time. S3 may be added when it is available in the FSP. All other features and IO ports are functional. Booted on Ubuntu 12.04 and 13.04, Fedora 18 with SeaBIOS payload. Memtest86, FWTS, and other tests pass. Board support page will be updated on acceptance.

Patch set updated for coreboot: dedd36c Add Intel FSP bd82x6x southbridge support
by Marc Jones 23 Nov '13

23 Nov '13

Marc Jones (marc.jones(a)se-eng.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/4017 -gerrit commit dedd36cf7ab95f49b09ad544f4589f109b6b0240 Author: Marc Jones <marc.jones(a)se-eng.com> Date: Tue Oct 29 22:12:32 2013 -0600 Add Intel FSP bd82x6x southbridge support Add support for the bd82x6x using the Intel FSP. The FSP is different enough to warrant its own source files for now. The mrc/system agent chromebook solution does much more southbridge initialization and configuration than the FSP version. It may be combined in the future.

Patch merged into coreboot/master: 617f853 lib/coreboot_table: set type and size of framebuffer tag after fill_lb_framebuffer
by gerrit＠coreboot.org 23 Nov '13

23 Nov '13

the following patch was just integrated into master: commit 617f853ae43ce1c15fbec1ecba2aa5624f6b4c7d Author: Vladimir Serbinenko <phcoder(a)gmail.com> Date: Sat Nov 23 14:46:34 2013 +0100 lib/coreboot_table: set type and size of framebuffer tag after fill_lb_framebuffer When testing Ron's patch on qemu I found out that fill_lb_framebuffer overwrites size and tag fields. We need either to fix/check all fill_lb_framebuffer implementations or write tag/size after fill_lb_framebuffer. I prefer later as it's more robust.

Patch merged into coreboot/master: 75b90a1 Remove MRC variables from 2065x CAR init.

the following patch was just integrated into master: commit 75b90a1f50f15b8ccb814d005c840d189d512f26 Author: Vladimir Serbinenko <phcoder(a)gmail.com> Date: Thu Nov 14 18:49:26 2013 +0100 Remove MRC variables from 2065x CAR init. 2065x boards don't use MRC. And the space in question isn't used either. Read number of variable range MTRRs from MSR rather than hardcoding it. 2ff is still zeroed out as unless you zero-out undocumented bits as well boot fails. Tested on Lenovo X201.
