I don't know why, but removing this BL31 make argument lets gru-kevin
power off properly when shut down from Linux. Needs investigation.
Do it as a cros-only HACK patch so people don't have to hold the power
button after every shutdown.

Debian's signed shim allocates too many EFI variables to fit in the EFI
variable memory buffer. Normally it would then try to continue booting
in non-secure-boot mode, but its error handling throws a synchronous
abort that reboots the board, making it impossible to boot into Debian
unless one manually loads GRUB instead of shim. Increase EFI variable
buffer size to avoid triggering the bug.

turns out it's just picky ram.
errant reports of "no boot" (users did not have debug
dongles) were likely "bad" ram

fixes ./build boot roms all
in detect_firmware(), "set" is used to get values from
configs, to know if things like ME/MRC are needed
on some "board" configs under resources/coreboot/, no
actual coreboot configs are provided, because they are
used as a reference (coreboot revision, tree name etc)
for actual boards, with actual coreboot configs
when attempting to build for such a board, running "set"
on such non-existent files would cause a non-zero exit,
when we want zero. the non-zero exit then caused the
build/boot/roms command to fail, when running "all" if
it found, for example, resources/coreboot/cros/ which
has the above problem, in this context
work around it by verifying that coreboot configs exist
for the given target name, in the blobutil download script.
if no such configs exist, then exit zero (success)
doing so is correct, because the script is intended to
do just that, erroring only if it is detected that blobs
are needed for a given board, but other errors occur; if
no coreboot configs exist, then no roms will be built and,
therefore, no blobs are needed

script is -e anyway, so this is redundant, but best
put it here anyway. it can only help. correct behaviour
is always to fail on error, except in certain cases that
would be handled on a case-by-case basis in each script
From now on, the following rules are available for all
mainboards, in resources/coreboot/boardname/board.cfg:
* blobs_required="n" or "y"
* microcode_required="n" or "y"
The blobs setting, if set to "n", simply renames filename.rom to
filename_noblobs.rom.
The microcode setting, if set to "n", copies the ROM (with or
without _noblobs) to filename_nomicrocode.rom (if blobs="n",
it would be filename_noblobs_nomicrocode.rom).
Where "nomicrocode" is set, ROMs with microcode will still be
provided by lbmk and in relesase, but ROMs will also be provided
alongside it that lacks any microcode updates.
If the *original* ROM already lacks microcode updates, then the
original ROM will be *renamed* to include "nomicrocode" in the name.
This is done on images for ARM platforms, for instance, where
microcode is never used whatsoever.
Example filenames now generated:
seabios_e6400_4mb_libgfxinit_corebootfb_noblobs_nomicrocode.rom
seabios_e6400_4mb_libgfxinit_corebootfb_noblobs.rom
seabios_withgrub_hp8300usdt_16mb_libgfxinit_corebootfb_colemak_nomicrocode.rom
seabios_withgrub_hp8300usdt_16mb_libgfxinit_corebootfb_colemak.rom
uboot_payload_gru_kevin_libgfxinit_corebootfb_noblobs_nomicrocode.rom
A vocal minority of people were not happy with some of the changes
made in Libreboot last year, including on existing supported
hardware from before those changes were made. I did this before the
last release, out of respect:
https://libreboot.org/news/gm45microcode.html
(re-add mitigations for no-microcode setup on GM45)
This new change is done as an further, extended courtesy. Tested
and works fine. (testing using cbfstool-print)
Actual Libreboot policy about binary blobs is nuanced. See:
https://libreboot.org/news/policy.html (reduction policy) and:
https://libreboot.org/freedom-status.html (implementation)
Well, the status page talks about descriptor vs non-descriptor
on Intel platforms, and where me_cleaner is used (on platforms
that need Intel ME firmware), it regards the descriptored setups
to be blob-free if coreboot does not require binary blobs.
In this paradigm, microcode updates are not considered to be
binary blobs, because they aren't technically software, they're
more like config files that just turn certain features on or off
within the CPU.
However, for lbmk purposes, "noblobs" means that, after the ROM
is fully ready to flash on the chip, there will be no blobs in
it (except microcode). So for example, an X200 that does not
require ME firmware is considered blob-free under this paradigm,
even though Libreboot policy regards X230 as equally libre when
me_cleaner is used; in this setup, ROMs will not contain "blobfree"
in the filename, for X230 (as one example).

Still on Gerrit. ME downloader failed with HP update file, so let's just
use Lenovo's instead. Both contain identical ME8_5M_Production.bin files.
Tested and working:
* Native raminit with both DIMMs
* Libgfxinit textmode and framebuffer on both DisplayPorts and VGA
* External USB2 and USB3 ports: they all work
* USB 3.0 SuperSpeed (rear, 4 ports)
* Ethernet
* Mini-PCIe WLAN
* SATA: 2.5" SSD and optical drive bay
* SeaBIOS and GRUB (boot to linux)
* PS/2 keyboard and mouse
* S3 suspend and resume, wake using USB keyboard
* Headphone output, line out, internal speaker
* Wake on LAN
* Rebooting
* CMOS options & nvramcui
Untested:
* Line in, mic input
* MXM graphics card
* EHCI debug
Not working:
* Mini-PCIe USB: I couldn't get it working on vendor BIOS either, so
maybe it just isn't present
* PS/2 keyboard wake from S3
* mSATA (I have no mSATA drives)
Tested with Johan Ehnberg (johan@molnix.com)
The following is tested and confirmed working:
- backlight control
- touchpad
- USB (external, smart card, fingerprint, bluetooth, webcam, WWAN)
- touchpad
- Wi-Fi
- 2,5" SATA
- USB 3.0
- SD card
- Memory: 2+2 (matched or unmatched), 8+2, 8+8
- internal flashing from libreboot
- SeaBIOS and GRUB payloads
- Boots Devuan and Ubuntu
Untested:
- ExpressCard
- DVD
- dock
- external displays
- eSATA
- trackpoint (not present on this aftermarket keyboard)
the loop in main() already checks EOF, and errno is
properly handled at the end of main()
we only need to call ferror(), to check error state
this fixes a bogus error message when pressing ctrl+D
to terminate the program, *which is the intended way
to terminate this program* (that, or EOF is reached
in any other another way)
do not treat intended behaviour as an error condition!

This reverts commit a4ea286731.
The licensing audit has been abandoned. I will not be re-licensing
in bulk to MIT.
I can still use MIT license on new works, e.g. utilities, but there's
really no pressing need to re-license lbmk. It's just shell scripts,
and most of what it interacts with (coreboot, grub, seabios) is GPL
anyway.
So who cares?
Ferass's patch was removed due to refusal to re-license, but the
decision to re-license has been canceled.
I'm now aiming for a quick stable release.
This fixes the PCI interrupt routing tables for the E6400 so that the SD
card works. It is already merged in upstream but libreboot has not yet
updated coreboot.
- A spurious semicolon caused the arguments to printf in die() to be
executed instead of printed
- ${@} in die() needs to be in quotes or else printf prints each word on
a separate line
- The number of arguments to main() does not include main itself so it
should be comparing against 1 instead of 2 to determine if enough
arguments were supplied.
i forked spkmodem-recv from coreboot, who forked it from
gnu grub. gnu grub's version has the full header, with
copyright declared as belonging to the fsf
coreboot made changes after forking it, and later replaced
the license declaration with an equivalent SPDX header, but
they also removed the FSF's copyright declaration, which by
itself does not void the declaration
anyway, i just feel better re-adding the full declaration.
make it so!
