WIP: chromebook integration script

2025-11-14T18:22:51+00:00

I intend to merge every Chromebook that Mrchromebox supports,
into Libreboot, ready for the Libreboot 25.12 release. Work
is still ongoing, and several changes need to happen in lbmk.

I started working on it a few weeks ago (today is
14 November 2025 as I push this).

Still TODO:

* Automatically create lbmk coreboot targets, based
  on the configs present in MrChromebox git
* Re-work git repository management in lbmk, such that
  a list of upstreams is used, instead of a hardcoded
  list per configuration; this will allow us to use
  different remotes across the same project, even where
  they diverge. This would then allow us to use the
  MrChromebook repository directly, instead of cherry-picking
  patches into upstream coreboot
* The note above about remotes would also mean that we can
  use MrChromebox's own edk2 repository directly. All of this
  would reduce the burden on lbmk.git
* Support building edk2 payloads, exactly mirroring the
  setups used on MrChromebox builds

There are some things that need to be checked first, for
boards that use MMC-based or eMMC-based storage, for the
GRUB and SeaBIOS payloads, also U-Boot, because I will
also be using these.

As such, this current script shall sit in lbmk master, but
it is not yet finished.

xbmk: tidy up some if statements

2025-09-25T23:09:46+00:00

this is an extension of the previous work to unroll
most of the condensed code lines.

make notices a bit more readable

2025-09-24T19:14:51+00:00

add line breaks, so that the license and author are
visually separated. this makes it easier to read.

xbmk: much more verbose error messages

2025-09-13T12:27:47+00:00

use the new functionality in err(), whereby a given
function name and arguments can be provided, for
debugging purposes.

something similar was already done in a few places,
and replaced with this unified functionality.

this patch will make xbmk much easier to debug, under
fault conditions.

mk: hardened PWD check (deny symlinks)

2025-09-05T10:46:16+00:00

we check if the first argument is "./mk" and bail if not,
which forces you to be in the xbmk work directory.

however, this check is flawed because symlinks were still
possible.

this patch prevents a same-named symlink "mk" pointing to
the real mk from being used.

this hardening is necessary, due to several built-in
assumptions inherent within the design of xbmk.

xbmk: remove xbloc, re-use xbtmp instead

2025-09-02T05:29:20+00:00

we no longer separate them. xbloc was the on-disk
tmp directory, whereas xbtmp used to be in /tmp
which we assumed to be tmpfs (it may not be, but
often is on many workstation setups - and our
documentation recommended doing this).

as mentioned in the previous commit, benchmarking
shows little speed difference using tmpfs /tmp
versus on-disk /tmp, for our purposes at least.
therefore, the handling of tmp files is being
greatly simplified.

mk: simplify the main script check

2025-08-31T17:27:09+00:00

it's still not perfect, but now it's unambiguous.

the previous generic check was written based on the
fact that xbmk's main script used to also be called
via several symlinks, which is no longer the case.
