<h2>
Revisions for r20150126 (relative to r20150124)
</h2>
<p>
This is a bug fix release based on r20150124. It contains a few small changes:
</p>
<ul>
<li>grub.cfg: hardcode the list of partitions to search (speeds up booting considerably. GRUB regexp isn't very well optimized)</li>
<li>Docs (x200.html hcl): Remove incorrect information</li>
<li>Documentation (bbb_setup.html): Fix typos</li>
<li>
build-release: delete ich9fdgbe_{4m,8m}.bin files from ich9gen
<ul>
<li>
These were accidentically included in the r20150124 release. They
are generated from ich9gen so it's ok, but they don't need to be
in the archive.
</li>
</ul>
</li>
<li>Documentation (grub_cbfs.html): Looping in libreboot_grub.cfg (Add notes about it if the user copied from grub.cfg in CBFS.)</li>
<li>Documentation: refer to Guix as GNU Guix System Distribution or GNU GSD per advice from the Guix project.</li>
</ul>
<h2>

<ul>
<li>This means that the user does not have to install build dependency

<li>x60flashfrom5 (new), for X60 users upgrading from 5th/early release</li>
<li>Update flashrom</li>
<li>Update GRUB</li>
<li>
Updated coreboot-libre
<ul>
<li>i945: permanently set tft_brightness to 0xff (fixes bug on X60 where
turning up brightness at max would make it loop back to low brightness)</li>
</ul>
</li>
<li>
getcb: Revert X60/T60 to legacy backlight controls
<ul>
<li>The ACPI brightness patches were abandoned and obsolete.</li>
</ul>
</li>
<li>grub.cfg: Only load initrd.img if it exists. Add rw to linux line (for ProteanOS)</li>
<li>build: Only generate the GRUB configurations once (re-use on all images)</li>
<li>Only build 2 GRUB payload executables, re-use on all boards.</li>
<li>
resources/utilities/grub-assemble/gen.txtmode.sh: Use GNU BASH<br/>
resources/utilities/grub-assemble/gen.vesafb.sh: Use GNU BASH
</li>
<li>scripts (error handling): Replace exit with exit 1 (make debugging easier)</li>
<li>
Move most files in CBFS to GRUB memdisk, except grub.cfg and grubtest.cfg
<ul>
This reduces the space used in CBFS because coreboot compresses
its payloads with LZMA by default. grub.cfg is all that most users
will want to modify, which remains in CBFS.
</ul>
</li>
<li>docs/release.html Add DMP vortex86ex to list of candidates.</li>
<li>docs/release.html Add ThinkPad X201 to list of candidates.</li>
<li>New links added to docs/security/x60_security and docs/security/t60_security</li>
<li>lenovobios_secondflash: Warn if BUCTS is not present. (not a dealbreaker. Can just pull out nvram battery/coin).</li>
<li>lenovobios_firstflash: Fail if BUCTS fails. (anti-bricking precaution)</li>
<li>Removed obnoxious warnings from flashing scripts, improved documentation instead.</li>
<li>scripts (all): add proper error checking (fail fast, fail early. Do not continue if there are errors)</li>
<li>buildrom-withgrub: rename image to boardname_layout_romtype.rom</li>
<li>buildrom-withgrub: don't move cbfstool, execute directly</li>
<li>resources/utilities/grub-assemble: add French Dvorak (BEPO) keyboard layout.</li>
<li>Documentation: add docs/hardware/x60_keyboard.html (show how to replace keyboard on X60/X60T)</li>
<li>Documentation: major cleanup (better structure, easier to find things)</li>
<li>
docs/release.html: Remove Acer CB5 from list of future candidates.
<ul>
<li>
Too many issues. Chromebooks are crippled (soldered RAM/storage/wifi)
and have too many usability issues for the libreboot project.
</li>
</ul>
</li>
<li>docs/gnulinux/grub_cbfs.html Major cleanup. Usability improvements.</li>
<li>hocs/gnulinux/encrypted_trisquel.html: Fixed mistakes/typos. General improvements</li>
<li>
flash (flashrom script): remove boardmismatch=force
<ul>
<li>
This was put there before for users upgrading from libreboot r5
to r6, but also allows the user to flash the wrong image. For
example, the user could flash a T60 image on an X60, thus
bricking the machine. It's almost certain that most people
have upgraded by now, so remove this potentially dangerous
option.
</li>
</ul>
</li>
<li>Documentation: update compatibility list for X60T LCD panels.</li>
<li>docs/release.html: add note about X60 Tablet board in X60/X60s</li>
<li>docs/howtos/grub_boot_installer.html: small corrections</li>
<li>docs/howtos/grub_boot_installer.html: improved readability, fixed html errors</li>
<li>Documentation (macbook21 related): clean up</li>
</ul>

Critical tasks for future release
</h2>
<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>
X60: <b>ACPI PCC Probe Failed</b> message on linux-libre 3.19 and higher. Fix it.
<a href="https://bugzilla.kernel.org/show_bug.cgi?id=93171">Preliminary bug report (kernel, linux)</a>
</li>
<li>
X200: only framebuffer graphics work. This is fine, since it's what most people use,
but text-mode graphics initialization is currently broken, which means that
memtest86+ will require serial output or ehci debugging.
</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>.
</li>
<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>
Add proper GS45 raminit for enabling all X200S and X200 Tablets to work properly. See <a href="hcl/x200.html#x200s_raminit">hcl/x200.html#x200s_raminit</a>
</li>
<li>
Look into those machines:
<ul>
<li>
ThinkPad X201 - ME ignition is an issue. Watchdog for ME is an issue. Might be possible to disable watchdog in the flash descriptor
(soft straps).
</li>
<li>
T410S is supported but not yet merged. This uses the same chipset as the X201.
<a href="http://review.coreboot.org/#/c/7975/">http://review.coreboot.org/#/c/7975/</a>
has the patch. This should be tested by someone and should ideally be merged in coreboot. pecg has one. help him.
</li>
<li>
ThinkPad R400/R500/T400/T400S/T500: see <a href="hcl/x200.html#new_targets">hcl/x200.html#new_targets</a>.
<ul>
<li>T400S might be GS45, and it might be using a wson-8 form factor for the flash chip.</li>
</ul>
</li>

This page contains a list of basically every thinkpad that would ever be a candidate for libreboot:
<a href="http://psref.lenovo.com/WithdrawnBook">http://psref.lenovo.com/WithdrawnBook</a> -
take a look at <a href="http://www.lenovo.com/psref/pdf/ltwbook_2013.pdf">this PDF</a>.
</li>
<li>
Lenovo G505S - might need video bios and microcode updates. These would have to be removed and/or replaced to be in libreboot
<a href="https://github.com/alterapraxisptyltd/lenovo-g505s">https://github.com/alterapraxisptyltd/lenovo-g505s</a>.
It's AMD (not Intel) based on the same design as the HP Pavillion 1035DX. No ME/AMT to worry about!

</li>
<li>
F2A85-M and E350M1 (libreboot_*_headless.rom). Test openatom. SMU firmware is a problem. XHCI firmware is a problem.

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.

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>,

He also uses the sigrok logic analyzer (free/libre):

</li>
<li>Add cubieboard SPI flashing instructions to libreboot.
<a href="https://github.com/mrnuke/coreboot/commits/cubie_mmc?author=mrnuke">mrnuke's github page with patches</a>. mrnuke in IRC knows
about the cubieboard</li>
<li>Memtest86+ is currently broken in text-mode. investigate</li>
<li>Todo: modify memtest86+ to work with libpayload (coreboot framebuffer) and delete all the text-mode ROM images.</li>
<li>linux 3.18 broke acpi brightness on i945. Libreboot reverted to legacy brightness for now. Look into why it
broke on 3.18 (do a git bisect).</li>
<li>
Look at vortex86ex boards. See <a href="http://libreboot.org/vortex86ex">http://libreboot.org/vortex86ex</a>.
</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.</li>
