support redundant downloads, and enable inclusion of these
tarballs inside release archives, for offline builds.

when we download coreboot, we currently don't have a way to
download crossgcc tarballs, so we rely on coreboot to do it,
which means running the coreboot build system to do it; which
means we don't get them in release archives, unless we add
very hacky logic (which did exist and was removed).
the problem with coreboot's build system is that it does not
define backup links for each given tarball, instead relying
on gnu.org exclusively, which seems OK at first because the
gnu.org links actually return an HTTP 302 response leading
to a random mirror, HOWEVER:
the gnu.org 302 redirect often fails, and the download fails,
causing an error. a mitigation for this has been to patch the
coreboot build system to download directly from a single mirror
that is reliable (in our case mirrorservice.org).
while this mitigation mostly works, it's not redundant; the
kent mirror is occasionally down too, and again we still have
the problem of not being able to cleanly provide crossgcc
tarballs inside release archives.
do it in config/submodules, like so:
module.list shall say the relative path of a given file,
once downloaded, relative to the given source tree.
module.cfg shall be re-used, in the same way as for git
submodules, but:
subfile="url"
subfile_bkup="backup url"
do this, instead of:
subrepo="url"
subrepo_bkup="backup url"
example entries in module.list:
util/crossgcc/tarballs/binutils-2.41.tar.xz
util/crossgcc/tarballs/gcc-13.2.0.tar.xz
util/crossgcc/tarballs/gmp-6.3.0.tar.xz
util/crossgcc/tarballs/mpc-1.3.1.tar.gz
util/crossgcc/tarballs/mpfr-4.2.1.tar.xz
util/crossgcc/tarballs/nasm-2.16.01.tar.bz2
util/crossgcc/tarballs/R06_28_23.tar.gz
the "subrev" variable (in module.cfg) has been renamed
to "subhash", so that this makes sense, and that name is
common to both subfile/subrepo.
the download logic from the vendor scripts has been re-used
for this purpose, and it verifies files using sha512sum.
therefore:
when specifying subrepo(git submodule), subhash will still
be a sha1 checksum, but:
when specifying subfile(file, e.g. tarball), subhash will
be a sha512 checksum
the logic for both (subrepo and subfile) is unified, and
has this rule:
subrepo* and subfile* must never *both* be declared.
the actual configuration of coreboot crossgcc tarballs
will be done in a follow-up commit. this commit simply
modifies the code to accomodate this.
over time, this feature could be used for many other files
within source trees, and could perhaps be expanded to allow
extracting source tarballs in leiu of git repositories, but
the latter is not yet required and thus not implemented.

in future revisions, i will make tarballs become subfiles,
to complement submodules. e.g. crossgcc tarballs in coreboot

copying the module list into tmpdir/ no longer makes sense,
because it was only done before when we supported either
running the list from "git submodule update", or module.list.
since we only support handling of module.list, we can
greatly simplify this function.

don't create elfdir, create dest_dir, which is elfdir
plus the location within it
only create dest_dir within copy_elf, which is only
called if actually compiling the code
this avoids creating empty elf directories, and it
generally cleans up all handling, unifying the
handling of directories into a single function,
namely copy_elf() which already exists

don't do it after, because that means the main project
is saved under src/ before we know whether the subrepo
was downloaded.
the "depend" variable (in config/git/) is no longer used
for projects that go in subdirectories of a parent; now,
we use config/submodules/ for this type of dependency.
download the "depend" projects (as per config/git/) first.
this way, if they fail, the main one will fail, but if
they succeed and main fails, you can just run the main
download again and it won't fail.
this fixes a bug where, depending on how you download a
set of projects and depending on the order which you do so,
a given project can become un-downloadable on current design,
because git will complain that a directory already exists.
this fix is done not only in code (by this commit), but
by prior configuration changes.

only use config/submodules/ which the build system then
uses to run git clones manually, replicating the submodules
feature. we must never use a project's own gitmodules feature,
because we can't easily control it. better to let it break first,
and then figure out what modules to add manually, so that we
have only what we need for each project.
it's done this way, because git's own submodules feature
doesn't have very good error checking in general, nor
does it have good redundancy.
with the current design, we can declare backup repositories
for each submodule.
we replicate it precisely. for example:
3rdparty/vboot
this is a coreboot submodule, and we handle that in the
coreboot trees.
however, our current design also allows you to do this even
if the upstream repository does not contain a .gitmodules file

we're not checking for bad elfs, but the check itself was bad

again: the "depend" variable must never be used for subprojects
that point to a subdirectory of the main project, because there's
no clean way of handling this in case of error conditions.
make it a submodule under config/submodules/. this is for the
documentation, including static site generator documentation,
and image files (photos).
as of this revision, there are now only those "depend" projects
defined in config/git/, where the destination directory of the
subject is not a subdirectory of the main project, so:
in a subsequest revision, i will mitigate an existing bug whereby
failure of the dependency project leaves the main one still
intact, breaking builds; this revision enables that to be done.
from now on, subproject-to-subdirectory-of-main-project will
be avoided in config/git/; config/submodules/ will be used.

same as the previous patch, we must no longer use "define"
variables in config/git/ when the path is a subdirectory of
a given project, because it means that the download can only
happen after the main one, and currently if that fails, the
download of the main repo would remain intact, breaking future
builds in ways that we can't control - to be clear, it could
be controlled, but with added code complexity in the build
system, so:
put it in config/submodules/
Signed-off-by: Leah Rowe <leah@libreboot.org>
don't define it as a "depend" variable in config/git/,
because it means putting the files in a subdirectory of
an existing project was was already then downloaded, and
that means it can't be downloaded first; if the download
of it fails, the old download is left intact.
this bug isn't currently fixed in the build system, at all,
so this and other patches are being made to mitigate it.

now it no longer hardcodes a check for whether the
project name is coreboot. this maintains the same
behaviour but will now work for other multi-tree
projects; in practise, the other multi-tree projects
did not use .gitmodules files anyway, but some of
them used config/submodules/ in our build system.

we already use config/data/grub to store grub config data

config/data/seabios

now multi-tree projects contain, per directory, just the
target.cfg file and the patches directory. this is much
cleaner, because some of the logic can be simplified more
Signed-off-by: Leah Rowe <leah@libreboot.org>
instead, check for the presence of target.cfg files
not in config/project/ but config/project/tree/
the way this check is done, it merely returns 1 if
config/project/*/target.cfg is detected, and returns
0 in all other cases, even if config/project/target.cfg
exists
that way, if the maintainer accidentally adds a
target.cfg in the main directory, the given multi-tree
project will not break

this avoids writing the version/versiondate files as root.
this complements the previous fix, that avoided writing those
same files when running the dependencies command.
initial setup of the build system requires root, to run the
dependencies script, but otherwise the build system prevents
running as root for everything else, so we must avoid writing
the version/versiondate files as root.
that same avoidance is necessary when checking whether running
other commands as root; ironically, this check then prevented
running the build system at all!
the bug should be fully fixed now. i found this quite by accident
the other day, when testing something else.
good thing this got fixed because the release!

do it strategically, in just the right place so that the
version and versiondate files aren't written.
otherwise, version/versiondate are written as root and
the build system becomes unusable after that, unless you
reset the file ownerships from root. hardly user-friendly.

already of saying "found", say "already exists"
this means the output of these commands more user
friendly and intuitive:
./update trees -b grub default
./update trees -b coreboot i945
this is just an example. when an ELF file already
exists, the build is skipped even if src isn't downloaded.
this design is intentional, because it means that you can
use previous builds if you want to save time on another.
