We don't really need a custom coreboot tree for Chromebooks. I had added
one, because at a cursory glance to the available config/coreboot/board
subdirectories I had the impression that I should. But upstreams have
one tree for every board and I think we should move towards that too.
Move the one important BL31 makefile patch into the default coreboot
patches, update the gru boards' configs by running savedefconfig in the
cros tree and then running olddefconfig in the default tree.

Add an "-s" flag for "make savedefconfig", "-l" for "make olddefconfig"
and "-n" for "make nconfig" to the update script. The first two are
mainly useful for U-Boot, to compare our configs to the upstream
defconfigs and stay in sync with any upstream changes. The latter is
because the ncurses one has a nice "Symbol Search" that can point out
the menu entry for a config symbol we know.

i wasn't getting the very first line of tar --version,
so it wasn't doing the check properly.
further sort the files by name within the tar archive.
for reliability, don't bother using versiondate anymore:
set a *fixed* date, and fixed timezone, to ensure
that it works reliably for reproducible tarball creation.

This way, the handling of configs is unified into one
script, which reduces the possibility of bugs later,
and it reduces the repetition of code.

e.g. src/coreboot/coreboot must not appear in a release,
because we instead have directories like
src/coreboot/default or src/coreboot/cros
lbmk resets src/coreboot/coreboot to HEAD, but then resets
revisions properly in copies of it
therefore, for reproducibility, we must not include
src/coreboot/coreboot, src/u-boot/u-boot or
src/seabios/seabios into libreboot releases

with --mtime, files added to the archive can be set
to a static date (in this case, the unix epoch)
the one used here is derived from git commit dates,
and it is static; if not being handled in lbmk.git,
the versiondate file never changes
this is the first patch in a series of patches designed
to bring about reproducible builds in libreboot
a solution will need to be found, for non-GNU tar
implementations, because they did not have an
equivalent option according to their manpages.
for example, BSD tar implementations.
perhaps i could systematically go around changing
file dates, on each file, as a fallback behaviour?

pass this argument: -m src
by doing this, only the src tarball will be made
Signed-off-by: Leah Rowe <leah@libreboot.org>
|
|
this way, the src tarball is guaranteed to be clean.
the downside is that lbmk itself does not currently
handle crossgcc downloads, and there may be some
stragglers such as third party modules automatically
downloaded by certain codebases that libreboot uses.
this will have to be audited later (and it will be).

it's sometimes done unconditionally. this change
ensures that it is not repeated needlessly.
i observed otherwise that cbfstool would be
re-built from time to time, even if it was built.

Riku's mSATA patch for HP8300USDT was merged upstream, so the
patch has been dropped from lbmk because it is contained within
this new coreboot revision.

coreboot closely matches upstream, whose current release
is version 1.2 from 2018, and coreboot has not changed it
in any meaningful way.
the upstream did add patches since, but they are documentation
patches only.
this means: we do not need to use the upstream version

also rename elf/coreboot to something scary
some users were flashing roms built under elf/, which
lack payloads. lbmk builds no-payload roms (and payloads)
under elf/ then inserts them, creating full (flashable)
images under bin/

The logic has been re-written, where source archives are
concerned. This clones the current repository, and starts
a new build from scratch. A custom release directory is
possible, by passing -d
This eliminates a step during build-testing, saving hours
of time, because it builds the release archive *inside* the
release archive, with git files removed, thus replicating
the same setup that the user would have.
This also makes everything a bit more consistent, because
it's guaranteed that a release archive will always have
the same files; previously, the release build script would
only copy what was already built, without building anything.
Now, this script builds everything itself.
The script also builds serprog images, not just coreboot.
Usage:
./update project release
If -d is not passed, release/ is used inside lbmk.
Otherwise, you could do:
./update project release -d /path/to/directory
If the directory exists, this script will exit (error).
Other minor fixes: build/fw/coreboot: make version in
coreboot-version (file) not contain hyphens, to work
around a quirk in coreboot's build system when not building
on regular libreboot releases. this quirk only appears
when lbmk is not being compiled under git.
The other main benefit of this change is that the new
script will probably require a lot less maintenance.

Just one script.
Just one!
Well, two, but the 2nd one already existed:
logic in update/project/trees and
update/project/repo was merged into
include/git.sh and update/project/build
was renamed to update/project/trees; an -f
option was added, which calls the functions
under git.sh
so git clones are now handled by the main build
script (for handling makefiles and defconfigs)
but the logic there is a stub, where git.sh
does all the actual heavy lifting
this cuts the file count down by two, and reduces
sloccount a reasonable amount because much of
the logic already exists in the build script, when
it comes to handling targets. git.sh was adjusted
to integrate with this, rather than act standalone

The benefit now is that it can be cleaned. E.g.
./update project build -b coreboot utils
./update project build -b coreboot utils default
./update project build -c coreboot utils
./update project build -c coreboot utils default
the update/project/build script checks when arguments
are provided after the project name. if the first one
is "utils", then it acts in the same way as the old
build/coreboot/util script

in the future, we may start downloading files that aren't
blobs, such as mxm port configs (on mainboards that use
MXM graphics)
this directory will contain all of those files
generally change the language used, across lbmk, to make
use of "vendorfile" instead of "blob"

build/release/src was partly re-written to accomodate this
memtest86plus was patched to have a central Makefile, and
lbmk modified to use that, rather than mess with build32
and build64. the central Makefile just builds both targets

Instead of having detailed error messages, run most
commands through a function that calls err() under
fault conditions.
Where detail is still required, err() is still called
manually. Where it isn't, the error message is simply
whatever command was executed to cause the error.
This results in a massive sloccount reduction for lbmk;
specifically, 178 sloc reduction, or a 8.1% reduction.
The total sloccount is now 2022, for shell scripts.
