re-add ability to use cbfs grub.cfg as default

2024-06-09T15:06:07+00:00

i removed this before, when making grub multi-tree,
because the design i used in an earlier version of
the patch actually added the grub.elf generation
to grub source itself, but then i decided to hack
around the grub build system from lbmk/cbmk instead

re-add this functionality, so that users can easily
insert their own custom grub.cfg into cbfs without
needing to re-build their image.

trees: exit with error if project undefined

2024-06-09T14:58:09+00:00

i was originally looser about this, because i also wanted
the trees script to generically run "make" from any
directory, but this behaviour was error-prone and it is
no longer used in the build system.

disable it, in the interest of stability.

add crossgcc tarballs to config/submodules/

2024-06-09T05:55:25+00:00

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

trees: simplified copy_elf() handling

2024-06-07T14:04:24+00:00

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

git.sh: download "depend" projects before

2024-06-07T13:16:58+00:00

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.

trees: fix build issue caused by bad elf check

2024-06-07T10:29:36+00:00

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

due to a quirk in how sh works. really, really obscure bug.

fixed now!

if the given directory didn't actually exist, or there were no
files in it, it'd be searching for the file named "*"

which is obviously wrong

trees: fix listfile check in copy_elf()

2024-06-07T09:35:38+00:00

don't check that the variable is empty

check that the file itself exists or not

this should fix the recent build issues

trees: don't say check elf/ if build.list missing

(on single tree projects. this complements the last patch)

trees: don't do elfcheck if build.list missing

2024-06-07T09:31:01+00:00

otherwise, some checks are done too soon, and nothing
gets built.
