adding to or removing from this list. (adapting the HTML should be simple enough)
</p>

<div class="section">
<h1 id="board_ports">Board ports</h1>
<ul>
<li>
Someone linked to
<a href="https://www.phoronix.com/scan.php?page=news_item&px=XGI-Coreboot-FB-Port">this news post</a>
about a PCI-E graphics card for which a free VBIOS replacement exists. This card uses the same
chipset as the onboard GPU in the ASUS KFSN4-DRE mainboard, which is already supported in libreboot.
This graphics card will allow certain desktop motherboards to be viable in libreboot.
</li>
<li>
<a href="https://lkml.org/lkml/2014/9/4/172">patch for linux (kernel) to add coreboot framebuffer support</a>
</li>
<li>
Libreboot has so far been biased towards Intel. This needs to end (the sooner, the better). A nice start:
<ul>
<li>
<b>ASUS KGPE-D16</b>: this is a very modern board. It has support for both Fam10h and Fam15h AMD CPUs. The board is still
new, and still in production. See
these coreboot mailing list posts:<br/>
<a href="http://www.coreboot.org/pipermail/coreboot/2015-April/079773.html">post 1</a> and
<a href="http://www.coreboot.org/pipermail/coreboot/2015-April/079773.html">post 2</a><br/><br/>
The board is fully functional (blobs not required), and will be an instant addition to libreboot.
See <a href="https://raptorengineeringinc.com/coreboot/kgpe-d16-status.php">https://raptorengineeringinc.com/coreboot/kgpe-d16-status.php</a><br/><br/>
<a href="http://raptorengineeringinc.com/content/base/main.htm">Raptor Engineering Inc</a> (USA) has ported
this board to coreboot, and is using the port internally on their computing cluster, for
the research that they do. This is the same company that ported
the <a href="hcl/kfsn4-dre.html">ASUS KFSN4-DRE</a> which is supported in libreboot.
The owner (and the
person who ported the board to coreboot), Timothy Pearson (tpearson on freenode IRC) has reached out to the community,
in request for funding. This funding will pay for the many months of work (at least 4-5 months, for over 10000
lines of code any many patches that will need to be split up) to get the code
upstreamed into coreboot. This is not as simple as just releasing the code; coreboot has a very strict code
review process (in place to ensure quality control). The patches will have to be split up, with people's
concerns and comments addressed over a long period, with patches constantly rebased to keep up with the
latest coreboot master branch. In order to get this done in a decent enough time frame, Raptor Engineering will need
to work on a more-or-less full-time basis. The funding amounts that he has asked for, are as follows:
<ul>
<li>35K USD - This pays for basic support (Fam10h)</li>
<li>+15K USD (stretch goal) - This pays for S3 (suspend/resume) and text-mode graphics initialization</li>
<li>+40K USD (stretch goal) - Fam15h CPU support</li>
</ul>
Although Raptor would be working for many months to get this upstreamed (merged in coreboot's master branch
in the git repository), libreboot would merge it more or less instantly, probably in the same week that the
code is released for review. Raptor would also of course be rebasing the patches on a regular basis, as part
of the review process, so even if it takes longer for the patches to be merged in coreboot, libreboot would have
support for this board.<br/><br/>
This is a <b>very</b> high-end board, making for a powerful server or workstation (desktop) system
that should easily be more than powerful enough for almost everyone. Timothy has replaced the AGESA
source in coreboot with native initialization code for AMD. The work that he has done can easily be
extended to support more hardware, so getting this code out and upstreamed is very important.<br/><br/>
Francis Rowe (lead developer of libreboot) is working with Timothy to get a crowd funding campaign started,
and trying to get as many people as possible interested in pledging towards the campaign.<br/><br/>
If you are interested in donating towards the campaign (once it begins), register your interest by contacting
Francis Rowe, using the information on the <a href="../contrib/">maintainers page</a>.
</li>
<li>
Lenovo G505S (works without CPU microcode updates).
Videos BIOS is not yet fully replaced (openatom doesn't have a working framebuffer, yet, but
it can draw a bitmap in user space, using a special utility) -
<a href="https://github.com/alterapraxisptyltd/openatom">openatom in github</a>.
SMU needs replacing (ruik/funfuctor/patrickg/mrnuke might be able to help).
</li>
<li>
F2A85-M and E350M1 (libreboot_*_headless.rom). Test openatom (video BIOS replacement). SMU firmware is a problem. XHCI firmware is a problem.
</li>
<li>
<b>TODO: Add ARM candidates here (the above systems are all AMD).</b>
<ul>
<li>Look into the <i>rockchip</i> (rk3288. note: mali gpu. one or two blobs might need replacing.
see <a href="http://blogs.coreboot.org/blog/2015/05/26/report-on-chrome-os-upstreaming/">this page</a>

That doesn't mean Intel is off the table just yet:
<ul>
<li>
ThinkPad R500
</li>
<li>
ThinkPad W500: they all use switchable graphics (ATI+Intel). Unknown if PM45 is compatible with GM45.
</li>
<li>
ThinkPad X61: ICH8, i965
lubko in #coreboot. <a href="https://github.com/lkundrak/coreboot/tree/x61">https://github.com/lkundrak/coreboot/tree/x61</a>
- raminit still isn't done, there might be other parts that need to be finished (probably EC).
This system comes with a ME, but it's optional like in GM45, and can be removed.

<li>
Non-lenovo GM45 laptops:
<ul>
Dell Latitude E6400 - quite a few of these online. This is a good laptop to target in coreboot and libreboot.
NOTE: EC support. ALSO: DDR2 memory (coreboot raminit for GM45 currently only supports DDR3)</li>
</ul>
</li>
<li>
<b>Desktop</b> system: Dell Optiplex 755. There are <b>lots</b> of these available online.
ICH9. DDR2 RAM (needs work in coreboot). No EC (it's a desktop). It will require
quite a bit of work in coreboot, but this is a very good candidate.
The ME can probably be removed and disabled, using ich9gen without any modifications
(or with few modifications). Where are the datasheets? Schematics?

<h1>Platform-specific bugs</h1>
<ul>
<li>
GM45: investigate S3/raminit on all models (CPU stepping/cpuid).
See <a href="hcl/x200.html#ram_s3_microcode">hcl/x200.html#ram_s3_microcode</a>
</li>
<li>
all thinkpads: When the system is running, plugging in an ethernet cable
doesn't always work (no network), you have to try several times. Booting with
an ethernet cable attached is reliable. Debug this and fix it.
</li>
<li>
KFSN4-DRE: investigate the 30 second bootblock delay.
<a href="hcl/kfsn4-dre.html#issues">More info</a>
</li>
<li>
KFSN4-DRE: jittery text-mode graphics.
<a href="hcl/kfsn4-dre.html#issues">More info</a>
</li>
<li>
Fix these issues on GM45/GS45 targets:
<ul>
<li>
X200: text-mode is broken. only framebuffer graphics work. Git-bisect is needed.
</li>
<li>
X60: on the latest coreboot-libre update lately (during June 2015), keyboard works intermittently.
Bisect and fix.
</li>
<li>
X200/X60: battery drained even while system is "off" on some systems. investigate.
Could just be the Ethernet controller waiting for a Wake-on-LAN frame.
'ethtool -s net0 wol d' disables wake on lan until the next boot. There are a lot of ways to make it permanent: netctl. systemd, udev, cron
</li>
<li>
Sound (internal speaker) broken on T500 (works in lenovobios). external speaker/headphones work.
- probably a different hda_verb
- <b>different HDA verbs are now used, test this again</b>
</li>
<li>
Fix remaining incompatible LCD panels in native graphics on T500 and T400.
See <a href="hcl/t500.html">hcl/t500.html</a>.
- EDID related, or difference in how VGA ROM does init. Investigate.
</li>
<li>
T400/T500/R400 (tested on T400): UART (serial port) doesn't work. Investigate.
(already tried enabling early h8 dock option. some RE with superiotool is needed).
- kmalkki has an R400. He says he can be contracted for it. (try to DIY first)
</li>
</ul>
</li>
<li>
<b>Finish all work listed in <a href="future/index.html">future/index.html</a></b>
</li>
<li>
Fix these issues on i945 targets (X60/T60/macbook21)
<ul>
<li>
i945: fix VRAM size (currently 8MB. should be 64MB).
See <a href="future/index.html#i945_vram_size">future/index.html#i945_vram_size</a>.
</li>
<li>
Fix remaining incompatible LCD panels in native graphics on T60.
See <a href="future/index.html#lcd_i945_incompatibility">future/index.html#lcd_i945_incompatibility</a>.
- EDID related, or difference in how VGA ROM does init. Investigate.
</li>
<li>
i945: the intel video driver used to initialize the display without native graphics initialization
and without the extracted video BIOS. It no longer does, so investigate why it does not, and fix
the regression (fix has to be done in the kernel, Linux).
See <a href="http://www.coreboot.org/pipermail/coreboot/2014-June/078104.html">http://www.coreboot.org/pipermail/coreboot/2014-June/078104.html</a> and

</li>
<li>
Add fake_vbt tables on i945 systems (also GM45).
</li>
<li>
Commit 26ca08caf81ad2dcc9c8246a743d82ffb464c767 in coreboot, see the while (1) loop that
waits for the panel to power up on i945. This is an infinite loop if the panel doesn't power up.
Fix it. Also, are there panels that don't power up? Test this, and fix it.

Add ProteanOS payload to systems with big enough flash chips. (eg X200/R400).

<a href="http://www.proteanos.com/doc/plat/porting/">http://www.proteanos.com/doc/plat/porting/</a>.

<h1>Build system</h1>
<ul>
<li>
add <i>resources/checksums/*</i> and update it whenever updating the modules
(coreboot, flashrom, etc) or updating patches.
For each download script, make it check the sha512 hashes of all the files, to ensure
that the files match the checksums.
</li>
<li>re-enable building of txtmode images (get memtest86 working again first, and fix gm45 txtmode)</li>
<li>
When downloading coreboot/grub/memtest/etc using the download scripts, it currently does
not check the integrity of these sources at all. Libreboot releases are signed, but
what can be done to improve it is to check the sha512sums of all files downloaded
by these scripts (which are in the git repository, but not the release archives,
because the release archives already include these sources). Do this for all
non-integrated modules used in libreboot.
</li>
<li>Make memtest86+ build using coreboot's own crossgcc toolchain. Currently,
memtest86+ doesn't even work at all when cross-compiled using the toolchain in x86-64 trisquel7</li>
<li>
Make libreboot (all of it!) build reproducibly. This is very important.
<ul>
<li>Talk to h01ger in coreboot about the coreboot part (he did reproducible.debian.net/coreboot/coreboot.html</li>
<li>
h01ger says ------ fchmmr: please keep the reproducible-builds@lists.alioth.debian.org mailing list posted - i'm aware of http://projects.mtjm.eu/work_packages/16 :-)
</li>
<li><a href="https://reproducible.debian.net/coreboot/coreboot.html">https://reproducible.debian.net/coreboot/coreboot.html</a></li>
<li>
check coreboot mailing list, eg:
<a href="http://www.coreboot.org/pipermail/coreboot/2015-June/079994.html">http://www.coreboot.org/pipermail/coreboot/2015-June/079994.html</a>
</li>
<li>
Check GRUB in Debian (or GRUB upstream) for how to make that reproducible
if Debian has done this already (they are working on reproducible builds)
- <b>h01ger says reproducible.debian.net/grub2</b>

<li>
Join #debian-reproducible on OFTC IRC.
</li>
<li>
merged in master (coreboot) - pay attention to these, especially
the fact that the reproducibility relies on git (libreboot uses coreboot without git,
and the reason makes this unavoidable):

not yet merged in master (coreboot:
<a href="http://review.coreboot.org/#/c/10515/">http://review.coreboot.org/#/c/10515/</a> --
not really relevant yet, but will be in the future. (libreboot currently ignores SeaBIOS)
</li>
</ul>
</li>
<li>
build/release/util currently fails on Parabola (it only works well in Trisquel).
- this should be made portable. Build (cross-compile all of the dependencies from upstream,
and include a <i>ccs/</i> release archive. Then use those for dependencies to cross-compile
everything (this should make portability easy, and there aren't a lot of dependencies
for the utilities).
</li>
</ul>
<p><a href="#pagetop">Back to top of page.</a></p>
</div>
<div class="section">
<h1>Improvements to the utilities</h1>
<ul>
<li>
Make ich9gen/ich9deblob portable. They both rely extensively on bitfields, and they assume
little-endian; for instance, mapping a little endian file directly to a struct, instead
of serializing/deserializing. Re-factor both utilities and make them fully portable.
</li>
<li>
Make ich9gen/ich9deblob/demefactory show GPL license info via <i>--version</i> argument.
</li>
<li>
Adapt linux-libre deblob scripts for use with coreboot. Libreboot is already deblobbed
using its own script, but updating it is still a bit too manual. linux-libre's deblob
scripts do an excellent job and (adapted) will make it much easier to maintain coreboot-libre.

BeagleBone Black
</h1>
<ul>
<li>Get libre distros ported to it. Eg proteanos, trisquel, parabola, librecmc and so on.</li>
<li>See <a href="https://coreboot.org/BBB_screwdriver">BBB screwdriver</a> - from the coreboot
project, this is an openwrt-based image for the BBB that comes with EHCI enabled out of the box.
Look into re-basing that on librecmc (librecmc is a deblobbed version of openwrt).</li>

<h1>Documentation improvements</h1>
<ul>
<li>
Next release after 20150518, relating to the ASUS KFSN4-DRE:
<ul>
<li>Remove the note in docs/release.html that says <i>NOTE: not in libreboot 20150518. Only in git, for now.</i></li>
<li>Remove the note in docs/hcl/kfsn4-dre.html that says <i> NOTE: This board is unsupported in libreboot 20150518. To use it in libreboot, for now, you must build for it from source using the libreboot git repository. </i></li>
</ul>
</li>
<li>
Next release after 20150518: note, mention that ACPI brightness methods for X60/T60 work again.
</li>
<li>
Get /proc/ioports for all hw logs. (this was added to Motherboard Porting Guide recently)
- other instructions were also added there. basically, get whatever extra logs are
desirable, for all systems.
</li>
<li>
Add info about FTDI FT232H usbdebug (BBB could be used for this):
<a href="http://review.coreboot.org/#/c/10063">http://review.coreboot.org/#/c/10063</a>
</li>
<li>
Add information from hw registers on all boards.
Get them for the following remaining boards: X60, T60, macbook21, R400
</li>
<li>
There are no instructions for how to use the GRUB terminal to find
a grub.cfg manually, or how to boot an installed GNU/Linux manually,
so some users get stuck after the initial installation of libreboot
not knowing how to boot the GNU/Linux system that they had before installing.
Fix that. (also, promote the FSF-endorsed distros while you do it)
</li>
<li>
Add guides for GM45 laptops in docs/security/
</li>
<li>
Add guides for GM45 laptops in docs/hardware/
</li>
<li>
Convert documentation to Sphinx/ReST
<ul>
<li>Translations are needed for the documentation and the main website.
Most people don't speak English as a first language.</li>
</ul>
</li>
<li>
LUKS key in initramfs: Add Trisquel documentation for docs/gnulinux/encrypted_trisquel.html.
</li>

<a href="http://blogs.coreboot.org/files/2013/06/superboosted2.jpg">image</a> -
work with mrnuke on getting info about vultureprog PLCC flashing into libreboot. Libreboot needs
server boards. <a href="https://github.com/mrnuke/vultureprog">https://github.com/mrnuke/vultureprog</a>,

<h1>Project (institutional) improvements</h1>
<ul>
<li>
Add proper guidelines for contributions,
like <i>Development Guidelines</i> on the coreboot wiki. For instance, require
<i>Sign-off-by</i> in all commits for libreboot. Consulting with the FSF about this
(licensing@fsf.org).
</li>
<li>
<b>Libreboot needs to be factory firmware, not the replacement. It needs to be *the* firmware.
Consult with the openlunchbox project (and maybe others) on getting hardware manufactured
with libreboot support (out of the box, from the factory).</b>
</li>
<li>
Set up a routine (project-wise) for testing each system with the latest kernel version.
</li>
</ul>

<h1>EC firmware</h1>
<p>
<a href="http://www.coreboot.org/Embedded_controller">http://www.coreboot.org/Embedded_controller</a>
Replace this on all libreboot targets. Some laptops use an extra SPI flash chip for the EC, some
have EC in the main chip, some don't use SPI flash at all but have the firmware inside the EC chip itself.
If the EC has integrated flash then you need to be able to get to the pins on the chip or be able to program them over LPC or SPI (if they have that feature).
The lenovo laptops currently supported in libreboot all use H8 EC chips (contains flash inside the chip).
Read the datasheets on how to externally programme the EC. Chromebooks seem to have free EC
(<a href="https://chromium.googlesource.com/chromiumos/platform/ec/+/master/chip/">https://chromium.googlesource.com/chromiumos/platform/ec/+/master/chip/</a>).
