remove variables that are not meaningfully used
Signed-off-by: Leah Rowe <leah@libreboot.org>
|

cbcfg is already a global variable, so there's no reason
to set it again at the start of this function.
remove the check for whether the given coreboot config
exists, to the calling function instead of build_roms().

the tmpcfg variable will be useful elsewhere, for
the same kind of change as before.

we don't need to call mktemp everytime.
just use a staticly named file in tmpdir
and keep overwriting it.
these files are only small, and they get deleted
when the build system exits later on.

build_grub_roms never returns a non-zero value
Signed-off-by: Leah Rowe <leah@libreboot.org>

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
Signed-off-by: Leah Rowe <leah@libreboot.org>

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.

adding help again is a bad idea. code should never
document itself; that's what documentation is for.
so, make the code do a better job telling the user
where to find documentation.

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.

this effectively lets you change the boot order. example:
./build roms -s "nvme ata" t1650_12mb
the above example would set:
grub_scan_disk="nvme ata"
another example:
./build roms -s nvme t1650_12mb
this would set:
grub_scan_disk="nvme"
this overrides what's set in target.cfg for the given
target. useful for quick reconfiguration if building
from source

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.

firstly, memtest86+ is currently not cross compiled and
relies on 64-bit headers (x86_64 only). a 32-bit distro
is unlikely to be able to build 64-bit binaries.
secondly: vboot throws a build error due to -Werror when
building on 32-bit hosts. we rely on vboot code to build
cbfstool, so turn off -Werror on vboot
that's all. 32-bit hosts are not recommended; it is assumed
that you are building on an x86_64 host. work will go into
the build system at a later date to make it more portable,
by cross compiling everything, but this should fix 32-bit
for now.
there are some x60/t60 users who still want to build roms,
so let's allow them that possibility.

an equivalent change has been made in cbmk.
certain lbmk-specific variable names have been made
generic, with certain functions and other variables
moved around.
i maintain sync between libreboot and canoeboot, where
both projects can have the same behaviours, and most of
the merge conflicts have to do with variable names
containing "LBMK", "lbmk", "cbmk" or "CBMK", or
indeed "canoeboot" and "libreboot"
LBMK/lbmk/CBMK/cbmk variables between canoeboot and
libreboot now contain the string XBMK/xbmk
it should now be *much* easier to merge build system
changes between lbmk and cbmk.

i always say, code should never document itself.
that's what documentation is for. the releases
contain documentation under docs/ but the git
repository does not; for that, use the website.
