the background is only a few kb. the whole rationale
before was to limit the space used in memdisk, but this
decision was made when the background was much bigger;
it has since been optimised greatly, and the grub modules
were heavily reduce, so it should be safe.
grub's memdisk breaks when you add too much data to it.
as part of simplifying the rest of lbmk, this change removes
some more bloat from the rest of lbmk. handling this in the
memdisk is much simpler than handling it with cbfstool.

add a generic function that can insert payloads with lzma
compression, or raw files without compression

if not inserted, the default keymap is usqwerty.
don't waste ssd write cycles copying so many images,
or cpu time compressing so many. the user can simply
add a keymap.gkb file to cbfs and it will work fine.
this will be documented in the next release.

rely on return status per each of the three main rom
functions, to then update the "targets" variable.
use this as the basis to determine which targets were
built, during final confirmation when the script exits.

the current validation check is extremely over-engineered,
because the user override is no longer available and we're
always very careful in how we modify target.cfg per board.
remove the redundant code. trust that target.cfg is correct.

p = payload
s = grub_scan_disk
d = displaymode
setting the payload is no longer safe, due to issue 216
and similar issues that might pop up in the future; it's
best left only to target.cfg, per board, so that we know
what config is safe/tested. don't let the user override it.
scandisk isn't safe to override because the given machine
may not have the type of device that the user specifies
displaymode is actually ok to set, because it simply whitelists
what configs pre-existing to actually use, but it's bloat
basically, the rule is this:
don't make it easy for the user to brick their hardware.
make it harder instead.
a user wily enough to go modifying their payload will probably
have read docs/maintain/ anyway and knows how to edit target.cfg
if they want another board configuration.

remove nvme support from the "default" grub tree
now there are three trees:
* default: no xhci or nvme patches
* nvme: contains nvme support
* xhci: contains xhci and nvme support
this is in case a bug like lbmk issue #216 ever occurs
again, as referenced before during lbmk audit 5
there is no indication that the nvme patch causes any
issues, but after previous experience i want to be sure

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.

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.

downloading it after means that if an error occurs
when downloading the xtree project, the main project
will still be there and nothing will mandate the
downloading of the xtree project. whereas, if we
grab the xtree project first, then the main project
won't get saved to src/
this makes the build system a bit more resilient under
fault conditions, but otherwise doesn't change behaviour.

don't say "file missing", because it may be present!
instead, say that the download failed. this covers both
contexts: internet failed and thus no file present, or
the file is present but checksum verification failed.
Signed-off-by: Leah Rowe <leah@libreboot.org>

on the initial check, the output is confusing because
it will say "checksum verification failed" if the
file doesn't already exist, but then goes to download.
only say checksum failed if a download occured, and the
check failed, otherwise report nothing except that the
file already exists.
this will not reduce the ability to debug issues later
on, and it will reduce the amount of confusion for users.

(#220) from fuel-pcbox/lbmk:master into master

support redundant downloads, and enable inclusion of these
tarballs inside release archives, for offline builds.
Signed-off-by: Leah Rowe <leah@libreboot.org>

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.

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

otherwise, it's not clear to the operator what's happening
i'm normally against such verbose feedback, because it's bloat,
but this minimal amount of feedback will make the build system
more pleasant to use, especially during testing.
