i have in fact tested whether many of these targets (ivy,
sandy and haswell on intel) boot without microcode, and many
do, but it's not as well tested
the older targets like i945, x4x, pineview and gm45 are
well-tested without microcode; ditto fam10/15h amd.
lbmk supports providing roms with and/or without microcode.
for the targets touched in this commit, lbmk now only
provides images with microcode included by default.
manual removal (with cbfstool) is still possible, if you want
to do that.

The same ROM images that you flash on Intel GPU variants,
are now flashed on Nvidia models. The same ROM will work
on both. If an Intel GPU variant is present, libgfxinit
is used, and the VGA ROM is used if an Nvidia GPU variant;
however, release ROMs will scrub the nvidia option ROM,
so release ROMs will only work on Intel GPUs unless you
run the blobutil inject command.
I decided to no longer have this under WIP, but to put
it in master. The issue with it pertains to video drivers,
which is not Libreboot's problem.
Nouveau crashes under Linux, so use "nomodeset" if it does.
The "nv" drivers in BSD systems work very well.
The nvidia model of E6400 isn't recommended for other
reasons, namely: poor thermal cooling (thermal pad on
the GPU) and that Nvidia GPU doesn't get very good
performance on any libre drivers anyway. The Intel GPU
variant is better, in terms of power efficiency and
software support; the intel variant also works with
native graphics initialisation in coreboot.
This board port already only enables SeaBIOS, which will
simply execute the VGA ROM. Blobutil already supports
reading the config, detecting that a VGA ROM is needed,
because that part of the WIP E6400 branch was already
merged in lbmk master.

lbmk never needed a makefile, because the build system
is all shell scripting; the former makefile simply called
those scripts, in a way that was mostly superfluous

some scripts in lbmk weren't cleaning up the tmpfiles they
made, and they still don't, but this mitigates that.
now in follow-up commits, i can start cleaning up those
scripts too.

libreboot's build system, lbmk, *is* available to use
in releases aswell (use the _src tarball), but it is
mostly intended for development, in lbmk.git
well, there's not much point wasting time / disk space
generating no-microcode roms within lbmk
they should be generated only at release time, alongside
the default ones
this patch implements that, thus speeding up the build
process and saving disk usage during development
the other alternative was to add a new option in
build/boot/roms, -m, that would opt in to removing them,
but this is extra complexity for something that is ill
advised and only provided to appease certain people

new behaviour:
* grub.cfg and grubtest.cfg no longer inserted to cbfs
* grub.cfg in memdisk instead
* grub.cfg in memdisk defers to cbfs/grub.cfg if added
(not added by default, anymore)
* does not defer to grubtest.cfg even if available
* only shows link to grubtest.cfg if available,
as a menuentry item
keymaps:
if /keymap.gkb exists in cbfs, it uses that by default,
but by default this isn't added. instead, it looks for
a file named keymap.cfg and sources that, which then
sets the keymap to one that is located under memdisk.
this file is inserted for each rom, per layout.
if keymap.gkb and keymap.cfg both absent, grub.cfg in
memdisk shall defer to usqwerty as the default keymap
grub_scan_disk: grub.cfg looks for cbfs file "scan.cfg"
and sources that if found, which will be inserted with
the string: set grub_scandisk=setting_goes_here (based
on target.cfg, generated by build/boot/roms automatically).
If no scan.cfg is found, it defaults to "both"
The "background.png" file remains unchanged, and present in
CBFS, used by grub.cfg if present (and it is, by default)
This change actually *saves* space in CBFS, due to compression,
and means that the grub.cfg is now compressed heavily. This
is also safer, because now the user overrides grub.cfg by
adding it, and they can still add grubtest.cfg for testing
first. If they accidentally delete both configs from cbfs,
Libreboot will fall back to the one in memdisk which would
presumably not be deleted.
This also means that lbmk can now more easily be used by
other build systems, that just want the GRUB part to re-use
in their own project. For example, people who want to build
custom coreboot images without using Libreboot's build system.
This change also *speeds* up the build process considerably,
on the parts where ROM images are copied. It's less than half
a second now, whereas previously it took about 30-45 seconds
for ROM images to copy, because of grub.elf being re-added in
each ROM via cbfstool, where compression is used; I believe
the compression part is what caused slowness.
Much, much faster, more versatile builds.

After that, do not allow anything to run if the user is
root. This logic flow is more robust, and reduces the
chance of bugs in the future.
We must not permit the user to run lbmk as root.
Running it as root *is* possible, by just removing
the check, and wily enough users will do that, but
this behaviour in lbmk is good practise because it
prevents accidentally running as root. If the user
went into root just for installing dependencies, they
might accidentally forget to switch back. This is a
safeguard against such folly.

this was an oversight on my part. the script cannot be

lbmk's new style is inspired by the bsd coding styles:
top-down logic, main simplified to a skeleton showing
overall program structure, variables well-defined,
rigorous (yet deceptively simple) error checking.
this was attempted before, but caused problems; coreboot
wasn't being cleaned properly, and rather than audit it,
i simply reverted this back to the old style.
this is actually attempt number 5, because i made 3 more
attempts between then and this one. i've build-tested this
using "./build boot roms all" (which is what b0rked on
the first attempt, months ago). it should be stable(tm).
the code is much nicer to read / work on now. this is the
beating heart of lbmk. get this script wrong, and you break
all of libreboot.

With this change, about 54KB of compressed space is saved
inside of CBFS, on setups that use the GRUB payload.
The uncompressed saving is about 720KB, but payloads are
compressed inside each coreboot image, so the compressed
saving is much smaller. That 54KB saving means a lot,
especially on small (1MB or smaller) flash sizes.

and only where grub was already enabled; on boards
that did not enable grub, grub is still disabled
on desktops, it's possible that the user may insert
a graphics card. if their first payload was grub,
it won't work because lbmk doesn't configure coreboot
itself to execute vga roms at present
i found when testing t1650 (dell) that if a vgarom is
loaded from seabios (from a graphics card), the grub
payload still works; if booting in corebootfb mode,
text mode is still used when booting with the card
to decrease the probability of bricks with any given
set of users, make seabios the only payload that starts
first, but make grub available in the esc menu on seabios
it's possible to add a bootorder file and disable the
seabios menu, if you only want a grub payload accessible

lbmk is much more likely to crash now, in error conditions,
which is a boon for further auditing.
also: in "fetch", remove the downloaded program
if fail() was called.
this would also be done for gnulib, when downloading
grub, but done in such a way that gnulib goes first.
where calls to err write "ERROR" in the string, they
no longer say "ERROR" because the "err" function itself
now does that automatically.
also: listmodes/listoptions (in "lbmk") now reports an
error if no scripts and/or directories are found.
also: where a warning is given, but not an error, i've
gone through in some places and redirected the output
to stderr, not stdout
as part of error checks: running anything as root, except
for the "./build dependencies *" commands, is no longer
permitted and lbmk will throw an error
mrc downloads: debugfs output no longer redirected to /dev/null,
and stderr no longer redirected to stdout. everything is verbose.
certain non-error states are also more verbose. for example,
patch_rom in blobs/inject will now state when injection succeeds
certain actual errors(bugs) were fixed:
for example, build/release/roms now correctly prepares the blobs
hash files for a given target, containing only the files and
checksums in the list. Previously, a printf message was included.
Now, with this new code: blobutil/inject rightly verifies hashes.
doing all of this in one giant patch is cleaner
than 100 patches changing each file. even this is yet part
of a much larger audit going on in the Libreboot project.
