Leah Rowe 340eea0b1c grub: insert background in memdisk instead
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.

Leah Rowe a4328cb11f roms: remove dangerous runtime p/s/d options
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.

Leah Rowe c5441bb9f5 re-add ability to use cbfs grub.cfg as default
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.

Leah Rowe d43247683b git.sh: download "depend" projects *before*
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.

Leah Rowe 429e91f908 make GRUB multi-tree and re-add xhci patches
Re-add xHCI only on haswell and broadwell machines, where
they are needed. Otherwise, keep the same GRUB code.

The xHCI patches were removed because they caused issues
on Sandybridge-based Dell Latitude laptops. See:
https://codeberg.org/libreboot/lbmk/issues/216

The issue was not reported elsewhere, including on the
Haswell/Broadwell hardware where they are needed, but the
build system could only build one version of GRUB.

The older machines do not need xHCI patches, because they
either do not have xHCI patches, or work (in GRUB) because
they're in EHCI mode when running the payload.

So, the problem is that we need the xHCI patches for GRUB
on Haswell/Broadwell hardware, but the patches break
Sandybridge hardware, and we only had the one build of GRUB.
To mitigate this problem, the build system now supports
building multiple revisions of GRUB, with different patches,
and each given coreboot target can say which GRUB tree to use
by setting this in target.cfg:

grubtree="xhci"

In the above example, the "xhci" tree would be used. Some
generic GRUB config has been moved to config/data/grub/
and config/grub/ now looks like config/coreboot/ - also,
the grub.cfg file (named "payload" in each tree) is copied
to the GRUB source tree as ".config", then added to GRUB's
memdisk in the same way, as grub.cfg.

Several other design changes had to be made because of this:

* grub.cfg in memdisk no longer automatically jumps to one
  in CBFS, but now shows a menuentry for it if available

* Certain commands in script/trees are disabled for GRUB,
  such as *config make commands.

* gnulib is now defined in config/submodule/grub/, instead
  of config/git/grub - and this mitigates an existing bug
  where downloading gnulib first would make grub no longer
  possible to download in lbmk.

The coreboot option CONFIG_FINALIZE_USB_ROUTE_XHCI has been
re-enabled on: Dell OptiPlex 9020 MT, Dell OptiPlex 9020 SFF,
Lenovo ThinkPad T440p and Lenovo ThinkPad W541 - now USB should
work again in GRUB.

The GRUB payload has been re-enabled on HP EliteBook 820 G2.

This change will enable per-board GRUB optimisation in the
future. For example, we hardcode what partitions and LVMs
GRUB scans because * is slow on ICH7-based machines, due
to GRUB's design. On other machines, * is reasonably fast,
for automatically enumerating the list of devices for boot.

Use of * (and other wildcards) could enable our GRUB payload
to automatically boot more distros, with minimal fuss. This
can be done at a later date, in subsequent revisions.

Leah Rowe e1883f1d5a grub.cfg: use grub_scan_disk to set boot order
Previously, grub_scan_disk could set ata, ahci or "both",
which would make both be tried (ahci first). This worked
when we only dealt with ata and ahci devices, but now we
support nvme devices so the logic is inherently flawed.

Instead, use grub_scan_disk to store the boot order, e.g.:

grub_scan_disk="ahci nvme ata"

grub_scan_disk="nvme ata"

In the first example, it would make GRUB scan ahci first,
then nvme and then ata.

In the secontd example, it would make GRUB scan nvme first,
and then ata.

If "both" is set, or anything other than ahci/ata/nvme,
grub_scan_disk is now changed to "nvme ahci ata".

Actual grub_scan_disk entries in target.cfg files will now
be modified, to match each machine.

Leah Rowe d32968c731 trees: reset makeargs per target/project
it wasn't being reset before. when coreboot is being
built, i add to makeargs every time. if multiple targets
are being built, the make command would end up looking
something like:

make -C src/coreboot/default UPDATED_SUBMODULES=1 \
    UPDATED_SUBMODULES=1

(the parameter would be printed twice)

of course, this doesn't check whether that parameter is
added already in target.cfg for a given target, but that's
ok because i won't add that one in target.cfg

i baked it into the code, only when handling coreboot,
because that was easier than either putting it in makeargs
for every coreboot target.cfg, or again modifying the code to
handle that; the current solution is the cleanest.
