this same change has been applied, selectively, to
certain return statements. the general rule is this:
the return statement should only be used to direct
logic within a script, where certain non-errors
states are used to skip certain actions; the exit
command should *never* be used to return non-zero,
except by err(). in so doing, we ensure easier
debugging of the build system
also: strip_rom_image in build/release/roms was
running "continue" when a rom file didn't exist,
despite not being a while/for loop. i make it
return (non-error condition) instead
it's ok for a script to exit 0, where appropriate,
but perhaps a function could also be written for it

in update/blobs/download, i saw instances where
appdir was being deleted with rm -r, but the more
appropriate command would rm -Rf. this is now fixed.
other than that, i've mostly just simplified a bunch
of if statements and consolidated some duplicated
logic (e.g. if/else block for dependencies in
build_dependencies() of update/blobs/download
one or two functions and/or variables have been
renamed, for greater clarity in the code, also
removed a few messages that were redundant
used printf instead of echo, in a few places, also
fixed up the indentation in a few places

See file:
resources/scripts/build/defconfig/for
It is based on:
resources/scripts/build/payload/u-boot
The u-boot payload script has been deleted, as has the
seabios payload script; the build/boot/roms logic has
been heavily simplified too, by removing the logic for
building of elf files based on defconfig.
SeaBIOS, U-Boot and coreboot all use defconfig-type
infrastructure for their build systems, and they are
fundamentally the *same* in how to compile each codebase,
at least in an lbmk context, regardless of actual (and
very huge) differences in these codebases.
Several hundred sources-lines of code have been eliminated
by this change, drastically simplifying everything; U-Boot
payload compiling also now errors out when a single build
fails, instead of continuing. Also: build/boot/roms no longer
re-compiles a coreboot target that was already compiled,
which is the same behaviour observed for payloads.
(this means you must now manually delete a target, when you
wish to re-build it; the build/boot/roms logic now more or
less just runs cbfstool; blobutil is handled from
build/defconfig/for)
ALSO: Since crossgcc is now handled by build/defconfig/for, not
build/boot/roms, standalone compiling of u-boot is now possible.
This has been tested. You compile it like so:
./build defconfig for u-boot
or specific trees, e.g.
./build defconfig for u-boot default
One other consequence of this patch is that re-building the same
ROM image is now much faster, because the same builds are re-used
unless deleted. This could be useful when testing grub.cfg changes,
for example, if that's all you change. With things like ccache used
(not yet used robustly in lbmk), this could speed things up more,
depending on the codebase.
This patch demonstrates the raw power of lbmk; it is a very
simple and highly efficient build system, and now much more so!

they are downloaded in the same way, and compiled in
the same way!

Very nice ivybridge board that supports ECC RAM.
NOTE: I couldn't get onboard graphics working yet, but
this was confirmed working with a graphics card (in my
case nvidia quadra k420) booted in text mode on the SeaBIOS
payload. The GRUB payload also works, when loaded from SeaBIOS.
Therefore, this is a SeaBIOS-only board (as far as first payload
is concerned), but you can pick GRUB from the menu.
You could make it "GRUB-only" in practise by setting SeaBIOS
boot order to only load GRUB, and disable the SeaBIOS menu.
We refer to this as "SeaGRUB".
I've made lbmk use biosutilities and uefiextract, to
get at the SMSC SCH5545 Environmental Control (EC) firmware.
This firmware is needed for fan control. This is automatically
downloaded and extracted, from Dell UEFI firmware updates.
As with other blobs such as Intel ME, this firmware is then
scrubbed by the release build scripts. The blobutil "inject"
script can be used to re-insert it.
Of note: there is no fixed offset, but no other blobs to
be inserted in CBFS either, so the offset when re-inserting
on release ROMs should still be the same, and thus the ROM
checksums should match, when running blobutil inject.

This reverts commit a4ea2867319471d9fe7d4ee540881e0286b4d3cf.
The licensing audit has been abandoned. I will not be re-licensing
in bulk to MIT.
I can still use MIT license on new works, e.g. utilities, but there's
really no pressing need to re-license lbmk. It's just shell scripts,
and most of what it interacts with (coreboot, grub, seabios) is GPL
anyway.
So who cares?
Ferass's patch was removed due to refusal to re-license, but the
decision to re-license has been canceled.
I'm now aiming for a quick stable release.
|
|
The primary purpose of my intense auditing has
been to improve lbmk's coding style and fix bugs
but there is a secondary purpose: know precisely
who owns what, because I want to re-license as
much as possible of lbmk under *MIT*, instead of
the current GNU licensing. MIT is vastly superior,
because it grants *actual* freedom to the user,
permits *sublicensing* and it is vastly more
compatible with other GPL combinations; for
example, MIT license is compatible with GPL2-only
whereas lbmk's current mix of GPLv3-or-later and
GPLv3-only is legally incompatible with GPLv2-only.
Re-licensing under MIT will most likely result in
more contributions to Libreboot's build system in
the future, especially as it will attract a lot
more commercial interest. Contrary to the popular
arguments, copyleft is a liability to the free
software movement and results in less code being
written; in practise, permissively licensed code
gets more public contributions, including from
commercial entities, even if companies can
theoretically make something proprietary out of
it (in practise, anyone inclined can just use the
upstream and proprietary forks almost always die).
Copyleft propaganda is fundamentally flawed. See:
<https://unixsheikh.com/articles/the-problems-with-the-gpl.html>
Anyway, I've been doing a combination of:
* Seeking permission from other copyright holders,
for re-licensing
* Deleting, or moving, other contributions; for
example, splitting certain contributions into
separate files so that originally modified files
become unencumbered. This latter solution is a
result of *code cleanup* arising from the audit.
For Ferass's contributions, I opted to seek
*permission*, and permission was denied. In full compliance
with this legal imperative, I'm acting accordingly; this
commit removes all of Ferass's changes that converted lbmk
to posix shell scripts, thus removing his copyright on the
affected files, bypassing his authority entirely. Therefore,
lbmk is largely now bash-dependent. In practise, nobody is
going to use anything other than a GNU system to build
Libreboot, because many projects that Libreboot makes use
of rely heavily on GNU; for example, coreboot's build
system makes heavy use of GNU-specific extensions in *GNU
Make*, and likely contains many bashisms. Of course,
Libreboot also compiles GNU GRUB.
I would much rather have MIT-licensed Bash scripts
than GPL-licensed posix SCL scripts.
This reverts the changes from Ferass El Hafidi,
for the following commits, with some exceptions:
* 7f5dfebf7d37c56d9c7993aaa17c59070cb5aec9
* f787044642236917c9c4dbcaa48a6b0648097db0
Exception:
download/mrc not reverted, because that was
already a fork of an existing script under
coreboot's build system, and their script was
GPLv2. i cannot/will not re-license this file
(ergo,
7f5dfebf7d37c56d9c7993aaa17c59070cb5aec9
change remains intact, on this file)
resources/scripts/build/boot/roms_helper, these changes
have been kept:
* 7e6691e9 - Add ARMv7 and AArch64 support
* dec2d720 - add myself in the build/roms_helper script
(added 2021 copyright for the change below)
* b7405656 - Workaround for grub's slow boot
^ these changes will be re-factored, splitting them
out of the file into a new file. This will be done in
a future lbmk revision. (in some cases, it makes sense
to keep a change but split it, allowing the main file to
be re-licensed without the change in it)
This is part of a much larger series of
licensing audits. It's likely that lbmk will
be posix-compliant (in its shell scripts)
again some day, because I'm planning to rewrite
most of these scripts (the ones modified in this
patch), and many of them (e.g. individual download
scripts) are subject to future deletion in a planned
overhaul of the download logic for third party
projects.
In addition: these changes are being kept (no attempt
to re-license them will be made):
* cff081c6 - Fix grub's slow boot (1 year, 5 months ago) <Vitali64>
* 4c851889 - Add macbook*1 16mb configs (1 year, 6 months ago) <Vitali64>
Ferass's work that remains will be split into dedicated
files containing them, where feasible.
In the case of grub.cfg (for GNU GRUB), I don't care
because it's a script for an engine (GRUB shell) that's
under GPL anyway, so who really cares about MIT license.

libreboot moved to codeberg for git hosting,
and i didn't want to keep lugging around an
extra git repo just for one tiny project.

By making lbmk fully POSIX-compliant, it will be easier to port lbmk to

tianocore is a liability for the libreboot project. it's a bloated mess, and
