Introduction
============
Libreboot is a free/open source BIOS/UEFI replacement on x86 and ARM, providing
boot firmware that initialises the hardware in your computer, to then load an
operating system (e.g. Linux/BSD). It is specifically a *coreboot distribution*,
in the same way that Debian is a Linux distribution. It provides an automated
build system to produce coreboot ROM images with a variety of payloads such as
GNU GRUB or SeaBIOS, with regular well-tested releases to make coreboot as easy
to use as possible for non-technical users.
Libreboot provides many additional benefits such as fast boot speeds, greater
security and greater customisation, but the *primary* benefit
is [software freedom](https://writefreesoftware.org/learn).
*This* new release, Libreboot 20240225, released today 25 February 2024, is
a new *testing* release of Libreboot. The previous release was
Libreboot 20240126, released on 26 January 2024. The most careful and
iterative approach is being taken in current development, because a new stable
release is to be made available by the summer of 2024. Much of Libreboot's
current focus is purely on hardware support, since the build system is more
or less stable at this point (owing to all of last year's major code audits).
Today's release has had some testing already, on most of the boards, and should
run just fine. If you spot any issues, please report them on Libreboot's bug
tracker.

Work done since last release
============================
With the exception of pico-serprog and replacing flashrom with flashprog (more
on this later), the current upstream revisions remain unchanged, but this
release has fixed a few issues and added more mainboards, relative to last
month's release.
New mainboards
--------------
* **HP EliteBook 8560w** - added to lbmk by Riku Viitanen, using the coreboot port
written by Iru Cai, with Riku's MXM support added on top (more on this later)
* **Dell Latitude E5520** - added to lbmk by Nicholas Chin, using his own coreboot
port for this board (testing provided by `Minimum_Baseball_629` on reddit)
* **Dell Latitude E5530** - added to lbmk by Nicholas Chin, using his own coreboot
port for this board (testing provided by Martin Dawson)
* **Dell Latitude E6520** - added to lbmk by Nicholas Chin, using his own coreboot
port for this board (testing provided by Martin Dawson)
* **Dell Latitude E6420** - added to lbmk by Nicholas Chin, using his own coreboot
port for this board (testing provided by Martin Dawson)
* **Dell OptiPlex 9020/7020 SFF** (and XE2 SFF) - added to lbmk by Leah Rowe, using
the coreboot port implemented by Mate Kukri.
* **Dell OptiPlex 9020/7020 MT** (and XE2 MT) - added to lbmk by Leah Rowe, using
the coreboot port implemented by Mate Kukri - uses Haswell MRC, but testing
was also done on Broadwell MRC (not yet added to lbmk due to lack of XHCI
support in GRUB, whereas EHCI seems to work fine in the Haswell one - a patch
was also [submitted](https://review.coreboot.org/c/coreboot/+/80717) to
coreboot for review, fixing VGA decode on discrete graphics cards when the
Broadwell MRC is used - this patch too is not yet included in Libreboot).
SeaBIOS MXM INT15H interrupt
----------------------------
For Libreboot's new HP EliteBook 8560w support, MXM handling was added to
SeaBIOS. This was performed by Riku Viitanen, who also wrote this tool:
<https://codeberg.org/Riku_V/mxmdump/>
These laptops use upgradeable graphics cards in an MXM slot. The MXM
specification states that the MXM config can be provided in an i2c ROM (and
Libreboot would not have to handle that) or, in some cases, may be provided
in the main boot flash, and loaded using an INT15H interrupt.
The MXM config is used by the VGA Option ROM on the card, for configuring
things like ports / power management. Without it, running the option ROM
would result in an error on the screen, telling you that the MXM configuration
was not loaded. In some cases, you may be able to modify the ROM to bypass it,
or it would just "work" anyway - but with undefined behaviour.
With Riku's addition, this EliteBook 8560w now works perfectly. Coreboot has
had a port for some time, but without the MXM support - for now, it is only
available in SeaBIOS, so you must use *SeaBIOS* to run the VGA Option ROM (it
cannot yet be done directly from coreboot).
U-Boot release script
---------------------
The script at `script/update/release` now supports generating standalone
U-Boot source archives, like so:
./update release -m u-boot
The usual `-d` option also works, for specifying a directory other
than `release/`. Libreboot still provides U-Boot embedded within the larger
source release archive, and does not yet actually provide U-Boot as a
standalone project, but some people may find this useful.
Pico-serprog updates
--------------------
Riku Viitanen added support for controlling multiple chip-selects. With the
new functionality, you can set unused chipselects high. This is useful when
flashing externally on an Intel IFD-based system where the two flashes are
connected, but without resistors between the shared data lines - on these
systems, the other flash's chipselect is electrically *floating* which means
it's in an undefined state; the new version allows you to control all of them,
turning *off* the other chip. This is useful when flashing the ThinkPad W541.
Documentation is provided for this, in the pico-serprog README. Riku also
fixed this issue:
<https://codeberg.org/libreboot/lbmk/issues/182>
Flashprog now used, instead of flashrom
---------------------------------------
Nico Huber was unfairly banned from participation in the flashrom project, and
went on to create a new project called [flashprog](https://flashprog.org/). The
purpose of flashprog is to provide *stable* releases, with incremental
development over time, maintaining support for newer chips/devices, while
being careful not to break old ones. The new leadership of flashrom takes a
far less conservative approach; flashprog was initially released as a project
called *flashrom-stable*, and Nico was permitted to use the coreboot gerrit
infrastructure - permission which was later revoked, leading to flashprog.
The new leader of flashrom accused Nico of foul behaviour, while not providing
any evidence; this, at the same time that the two of them had seemingly
incompatible assumptions about the future of the project. It's pretty clear
what the real reason was for his *dismissal*, though the Libreboot project is
not taking Nico's side simply for personal reasons - no, it is because Nico has
a much better vision for the flashrom project, which he is now implementing in
the new flashprog project.
Several developers have already jumped ship and went to work on flashprog.
Nico's vision is a far more sensible one, and he has been invaluable to the
Libreboot project over many years. As a result, Libreboot withdraws its support
and endorsement of flashrom - it will only promote flashprog from now on.
It's quite possible that *flashrom* has a future, but there's no reason why
their changes cannot also be included in flashprog, if they are good changes,
moving forward. Libreboot supports Nico's work out of principle, both on
a social (community-led, not run by an employee of Google) and technological
perspective. This was done because, firstly Nico Huber is a better leader,
and flashrom is very likely to become the dominant project in the future.
This is the *first* Libreboot release to include flashprog sources, instead
of flashrom. Moving forward, we will *not* be providing support for flashrom.
Only flashprog. Libreboot's distribution of flashprog *also* includes the
macronix workaround (useful when externally flashing the ThinkPad X200).
Indeed, Nico's mentality has already proven to have merit; newer revisions of
flashrom *break* internal flashing on ThinkPad X60 and T60, last time it was
tested (some time during Q4 2023, on the latest git revision). Nico's flashprog
is rock-solid on these older platforms, while having already added several major
new features and hardware functionality - for instance, it has code for handling
Riku Viitanen's recent changes on the RP2040 serprog images, for pulling unused
chipselects high (useful on machines like ThinkPad W541 for external flashing).
