It is possible to install GNU Boot on I945 Thinkpads without opening
the computer even if the nonfree bios sets the bootblock region (the
last 64K of the flash chip) read-only.
The flash chip looks like that:
+----- -----+---------------------------+-------------------------+
| ... | Secondary bootblock (64k) | Primary bootblock (64k) |
+----- -----+---------------------------+-------------------------+
0 0x1e0000 2MiB
To bypass the read-only restriction we use an utility (bucts) that
tells the hardware to swap the primary bootblock with the secondary
one for the next boot. We then have to disable that swap and reflash
again.
CONFIG_INTEL_ADD_TOP_SWAP_BOOTBLOCK generates the two bootblocks
directly in coreboot so we don't need to use special commands to do
that anymore.
In addition the MacBook 1.1 and 2.1 are known not to have such
read-only restrictions so they don't need to have
CONFIG_INTEL_ADD_TOP_SWAP_BOOTBLOCK enabled.

The various scripts present in GNU Boot are very fragile, so it's a
good idea to have a pristine GNU Boot source code for making releases.
The issue is that 'git clean -dfx' doesn't remove existing git
repositories like coreboot/ grub/ etc, so we need additional code to
take care of that.

The various build scripts are scattered around in multiple
places. This make it hard for contributors to understand what they
need to modify.
Most GNU Boot users are interested in running GNU/Linux or BSD
operating systems. And the way to install software on these
operating systems is through a package manager. So most users and
contributors already know the package manager abstraction.
So using that abstraction makes it easier to find where things are.
The scripts to install dependencies don't really fit the new structure
but for now we move them in to make sure that everything works
fine. This could be fixed later on and migrated to a single
dependencies packages by auto-detecting the distribution with
/etc/os-release.

The "Load Operating System (incl. fully encrypted disks) [o]" GRUB
entry tries to load grub configuration files from the hard disk or SSD
partitions. It tries various files in /boot, /grub, /grub2,
/boot/grub, /boot/grub2.
For consistency we at least need to make it search for the
gnuboot_grub.cfg in these directories as well. Since this is GNU Boot,
the gnuboot_grub.cfg takes precedence over files made for other boot
software distributions.
For libreboot_grub.cfg, it was not replaced because it is still

This commit updates the coreboot code base from release 4.11 to 4.11_branch for kgpe-d16,
kcma-d8, kfsn4-dre and addresses one new blob related to this update.
The main reason to update the codebase is to prevent a bug with RAM initialization
that occured with coreboot 4.11 and raised the following critical error:

This coreboot revision also correct some bugs with SMM, SMBIOS, IPMI and BMC.
Some new values in coreboot configuration make coreboot first build stop to prompt
users and forcing them to choose an option to continue:
- CONFIG_STM
- CONFIG_DEBUG_IPMI
- CONFIG_VENDOR_VIA
- CONFIG_SOUTHBRIDGE_AMD_CIMX_SB900
- CONFIG_IPMI_FRU_SINGLE_RW_SZ
- CONFIG_IPMI_KCS_TIMEOUT_MS
A bug has been opened about CONFIG_STM on our bug tracker [1], and we decided,
for now, to unset this option explicitely.
So in this commit we just regenerated configurations for each fam15h board via
coreboot build prompts and copied the resulting configurations in the configuration
folder and that results in the following:
- unset CONFIG_STM
- unset CONFIG_DEBUG_IPMI
- unset CONFIG_VENDOR_VIA
- unset CONFIG_SOUTHBRIDGE_AMD_CIMX_SB900
- set CONFIG_IPMI_FRU_SINGLE_RW_SZ=16
- set CONFIG_IPMI_KCS_TIMEOUT_MS=5000

with this change, it's unlikely we'll hit errors again. previously,
some projects used were calling "python" which in context was
python3, but on some setups, the user only has python2 and python3
but no symlink for "python" (which if exists, we assumed linked to
python3)
now it's unambiguous. docs/build/ can probably be updated now, as
a result of this change, to remove the advice about that
I was running into a race condition when rebuilding seabios with a high cpu count,
resulting in failure with this error message:
cc1: fatal error: can't open 'out/src/asm-offsets.s' for writing: No such file or directory
Performing the silentoldconfig step before the full make step seems to resolve the failure.

This doesn't change the existing usage of the scripts:
- For the Coreboot script, before this change, all arguments that were
passed were considered as board to download the Coreboot source code
for.
Here we added the '--help' and '--list-boards' arguments, so it
should not be an issue as it is extremely unlikely that a board
would be called '--help' or '--list-boards'.
- All the other scripts don't use any arguments so passing --help
should not conflict with the existing usage.

Many people using FSDG compliant distributions or wanting to use one
are already familiar with linux-libre. This change renames the
resulting tarball to u-boot-libre to make it easier for people to
understand the goal of this tarball.
In addition we also rename the version from v2021.07 (which is the git
tag corresponding to the release) to 2021.07 as u-boot upstream
tarballs use that.
The revision wasn't bumped as we didn't have any releases of
u-boot-libre yet.

Once the tarball are released, it will enable distributions to use
these tarballs to produce deblobbed u-boot packages.
Note that the produced tarball is not reproducible yet. Because of
that it has to be trusted.
During a release, it's a good idea to sign the uncompressed tarball as
the various compression formats and associated tools make different
tradeoffs.
For instance with xz, xz -9e tends to compress really well with the
the most used xz[1] implementation, and most GNU/Linux users probably
already have it installed, but and the drawbacks is that the format is
very fragile[2].
The lzip format is more suited for long term archiving but its most
packaged implementation[3] is less likely to be already installed by
users than more well known formats like xz, bzip2 or gzip.
Being able to add more compression formats after the release is also
useful, for instance to accommodate different build systems or use
cases (like being able to build u-boot with less dependencies in
distributions like Guix, or building u-boot directly on devices which
don't have enough RAM for xz for instance).
