Hi Iru,
we aren't still sure which boards use Intel Boot Guard and which doesn't use it. But we expect most board use it,
because it's "recommended" by intel - as we dont recommend it.
Also there isn't yet a test script for Intel Boot Guard.
Can you post a link to that forum post?
I would like to look into a x240 flash image. If you have such board it would be nice
if you can send me a copy of the flash image via private mail.
Cheers,
lynxis

Hi,
we obviously want to participate in FOSDEM.
https://fosdem.org/2016/news/2015-09-24-call-for-participation/
ACT NOW!
Some deadlines already expired. Some can still be managed.
Main track talks: Deadline 2015-10-30 (10 days left)
One hour of entertainment, huge audience.
Anyone up for the challenge?
Stands: Deadline 2015-11-13 (24 days left)
I can send in the proposal if I'm not going to be alone there.
How many tables do we want for our stand/booth(s)?
Who is coming?
Lightning talks: Deadline 2015-11-27 (38 days left)
Short and to the point. Your 15-minute elevator pitch.
Can you sell the project?
All deadlines are at 23.59 UTC
Developer room proposal: Deadline EXPIRED
Maybe some developer room will accept talks/demos from us.

Over the past week or so, I've been working to get Libreboot running on
the latest ARM Chromebook: the C201, manufactured by Asus (codename
veyron_speedy). The laptop is running with a RK3288 SoC and ships with
Google's version of Coreboot preinstalled. It should require no
proprietary code nor any proprietary firmware load or microcode update
to boot, thus it would be a good fit for Libreboot, as a fully free
distribution of Coreboot.
In addition to that, the device's embedded controller (that handles
aspects of power management as well as the keyboard and a few other
things) is a microcontroller that is also running free software: the
free embedded controller firmware from Google.
Aside from that, it has a soldered Wi-Fi/bluetooth BCM4354 chip (cannot
be removed) that has a free driver but requires to load a proprietary
firmware on the chip. However, it is easy to work around that issue and
not use that chip at all, e.g. using an ath9k_htc dongle on one of the
two USB ports.
The GPU is a Mali T764, on which Luc has been doing some early work to
have free software support for it. It is uncertain[0] how long it will
take to have an usable free replacement for it, but now that there is
that hardware available, free graphics for Mali T GPUs would mean having
a recent laptop running fully free software, down to the firmware level,
without losing any major hardware feature, something that has hardly
ever been achieved yet. Thus, I believe it is of the utmost importance
to back Luc up on this, even if big players like ARM are trying hard to
make Lima not happen and to make it difficult for Luc to keep going.
Another aspect that I still have to look at in-depth is the ability to
use hardware video encoding/decoding. The RK3288 has an auxiliary
processor for that task, but it is unclear whether it can be used with
free software or not, though the first indications that I've gathered
are positive.
At this point, I've been able to boot up Debian on the device, and the
xfce4 interface is quite usable. It even runs big programs like
Iceweasel/Firefox and LibreOffice without inconveniences.
However, it cannot run desktop environments that depend on GL
acceleration, such as gnome-shell, which is a shame since those would be
a good fit for it. The CPU is simply too slow for offering a decent
experience with software rendering (llvmpipe).
Overall, I truly hope this device creates an incentive to free the last
remaining parts that can only work with proprietary software to this
day. Its potential would be huge, especially since it's a good fit for
travellers. With the security model inherited from Chromium OS, this
would be one of the safest laptops to be used by journalists or
activists. If Tails was to be ported to it, it would become easy to have
a secure and anonymous setup.
I have successfully fixed and compiled Coreboot and all the necessary
bits and pieces for the C201, so I'll be spending the next few days
sending patches, discussing how to integrate it to Libreboot and getting
the actual work done.
I also plan on documenting all my findings (especially things like how
to access UART, how to remove the SPI flash's write protect, how to
reflash it externally, etc) on my coding blog, for now.
Cheers!

Since 2009 is really only 6ys ago, I'm a bit hesitant about the VX800
stuff (while leaving the older CN700 / CX700 in the tree)
It also seems VIA gave up on coreboot at this point, so it might not
matter, unless we want to work on bringing them back?
Is anybody in contact with VIA at this point?

I want to add the following boards (and their chipsets and super ios)
that have been in the tree and basically unmaintained for 10+ys:
* arima/hdama

I think this is a hard problem. Churn on a board's or chipset's code
does not necessarily coincide with a board being used or the other way
around. A target might just be stable and working well.
We need to get to the point where 100% of the boards in the tree are
boot tested 100% of the time.

Hello Holger,
I am locking forward to flash coreboot to a cb5-311. So I was searching for
sources and information about it. The only thing i found was this cb5
unbricking mailinglist and the dev info.
How far did you get with the flashing of your cb5? Do you now have corboot
running your cb? Do you know some sources and information that would help
me?
Regards,
Robert Maucher
dev info:
https://www.chromium.org/chromium-os/developer-information-for-chrome-os-...
Nice job all. Patrick, I'm looking forward t the next release detailing how
many files and lines were removed :-)
include, oh sad, the 440lx :-)

Alex, I think this is a great suggestion, but as I have explained to you
in person before, from a perspective of reaching a legal agreement this
is almost equivalent (if not more effort) than working on an agreement
to open source that code to begin with. The coreboot project's objective
is not to reimplement what other people have done, but to change the
industry to create more open computing devices.
That said, if you want to drive an example terms of use with your
employer that fulfills your advanced criteria, you are more than welcome
to do so, and I believe it would serve as a role model in the silicon
industry.
I am happy to help with such an arrangement, and would be even happier
if we could just open source the code in question. But we can take this
offline.

Reverse engineering is impractical in all cases. Specifically this
document is focussing on what BLOBs we can ship in the 3rdparty/blobs
directory, not generally which BLOBs are allowed in coreboot.
In terms of many blobs (like FSP, hint hint), we are not even at the
point where we can redistribute them in 3rdparty/blobs yet. Adding
additional restrictions would, if anything, change nothing at all
(except that our users will have to get their own collection of BLOBs if
they want to participate).

I would like to get the existing BLOBs into 3rdparty/blobs first before
we talk about removing them in a year (e.g. FSP, hint hint).
All the best,
Stefan
(Halloween 2015 release - just as scary as that sounds)
Dear coreboot community,
today marks the release of coreboot 4.2, the second release on our
time based release schedule.
Since 4.1 there were 936 commits by 90 authors, increasing the code
base by approximately 17000 lines of code. We saw 35 new contributors
- welcome to coreboot! More than 34 developers were active as
reviewers in that period.
Thanks go to all contributors who helped shape this release.
As with 4.1, the release tarballs are available at
http://www.coreboot.org/releases/. There's also a 4.2 tag and branch
in the git repository.
This marks the first release that features a changelog comparing it to
the previous release. There was some limited testing to make sure that
the code is usable, and it boots on some devices. A structured test
plan will only become part of the release procedure of future
versions.
I'm grateful to Martin for assembling this release's changelog.
This is also the first release that will be followed by the removal of
old, unused code. There will be a policy on how to announce
deprecation and removal of mainboard and chipset code for future
releases.
Regards,
Patrick
