New patch to review for coreboot: 696cacf Add initial aarch64 support

Ronald G. Minnich (rminnich(a)gmail.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/4271 -gerrit commit 696cacfb22e4d5746ca681f11d41322b05cca533 Author: Ronald G. Minnich <rminnich(a)google.com> Date: Mon Nov 25 09:44:16 2013 -0800 Add initial aarch64 support This is for the aarch64 architecture. A followon patch will be for the ARM Ltd. v8 cpu implementation, followed by a mainboard. This builds but will require the two follow on patches and my recently submitted cbfstool patch if you wish to see what it looks like. It is missing critical support for functions such as memcpy, etc. but my goal is to get an early view of where it is going to the community. The initial test will be getting it to halt correctly.

Patch merged into coreboot/master: cae09e0 bochs: add support for native graphics
by gerrit＠coreboot.org 25 Nov '13

25 Nov '13

the following patch was just integrated into master: commit cae09e0bbe61417667685c93cccc761c7d727daf Author: Ronald G. Minnich <rminnich(a)google.com> Date: Tue Nov 19 17:42:41 2013 -0800 bochs: add support for native graphics Per our discussions with Gerd, qemu will now always do native graphics on coreboot. The VGA BIOS capability is not needed and will no longer be supported. Attempts to build without native graphics will result in an error. This code builds for both x86 emulation targets. I'm hitting an issue testing that is unrelated to coreboot; if someone can test, that would be helpful. Be sure to start qemu with -vga std. We also add a test for the PCI BAR being zero and return silently if it is. Change-Id: I66188f61e1bac7ad93c989cc10f3e0b55140e148 Signed-off-by: Ronald G.

Patch set updated for coreboot: ee1c944 Lenovo X201 support (mobo part)
by Vladimir Serbinenko 25 Nov '13

25 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 ee1c944204564559479a97639d2d3bc2de3fb3c3 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.

New patch to review for coreboot: 0c81b5b qemu: cirrus native video init
by Vladimir Serbinenko 25 Nov '13

25 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/4270 -gerrit commit 0c81b5bf7f65a3f8222ad7161295f7067bcd923e Author: Vladimir Serbinenko <phcoder(a)gmail.com> Date: Mon Nov 25 11:20:20 2013 +0100 qemu: cirrus native video init Recent commit proposal by Ron Minnich proposes to move to native gfx init for qemu. Unfortunately we didn't have native init for default qemu video (cirrus) Here is one extracted from GRUB one which I wrote couple of years ago.
