This is particularly beneficial for servers with Aspeed BMC video,
because it introduces framebuffer console acceleration. The
framebuffer console is much more responsive.
Patches were ported from 5.10.5:
0001-fake-acpi.patch: This may not be needed any more, but it applies
cleanly and I don't think it would harm anything.
0002-nmi-squelch.patch: The comment mentions qemu but I see this
message on physical machines occasionally, so I think this is needed.
0003-fake-trampoline.patch: This patch does not apply cleanly. It
could be ported, but I don't think it's needed, I dropped it. Dates
back to a very old commit where Linux was being embedded into a vendor
UEFI firmware: a4d7654b1e.
0010-winterfell-ahci.patch: Minor change of %x to %lx in context.

Bash uses .build to keep count of the build number, which conflicts
with heads build system usage of .build to keep track of built modules.
If .build already exists when bash/configure is run it will increment by 1
the build number. This is configurable on the call to the support script
support/mkversion.sh, which is called from the bash/Makefile.
Patching the Makefile template used during bash configuration allows
disabling the build number increment.

Update kexec to 2.0.26. Add tracing to framebuffer initialization. In
particular, the driver name is traced if not recognized, and messages
about kernel config are shown if the kernel doesn't provide the
framebuffer pointer.

The i915 driver's ID changed again, now to i915drmfb.
It's unclear why kexec checks this, it seems it could populate the
target kernel's framebuffer info as long as it knows enough about the
host kernel's framebuffer, which it already checks. Maybe we could
improve this, for now just add the new ID again.

The actual use of curl was already removed, update tpm2-tools patch to
also remove the check for curl. Remove the curl module and
CONFIG_CURL.

-coreboot support of TPM v2.0 (shared config for TPM2 support across all 4 previous variations)
-swtpm set to be launched under TPM v2.0 mode under board config
-Documentation file under each board.md softlinks to qemu-coreboot-fbwhiptail-tpm1.md (which has been generalized)
This is skeleton for TPM v2 integration under Heads
-------------
WiP
TODO:
- libcurl cannot be built as a tpm2-tools dependency as of now not sure why. curl currently needs to be added in board config to be built
- Note: tpm-reset (master and here) needs some review, no handle of no tpm use case. Caller is responsible to not call it otherwise does nothing
- init tries to bind fd and fails currently
- Note: Check if whiptail is different of fbwhiptail in clearing screen. As of now every clear seems to be removed, still whiptail clears previous console output
- When no OS' /boot can be mounted, do not try to TPM reset (will fail)
- seal-hotpkey is not working properly
- setting disk unlock key asks for TPM ownership passphrase (sealing in NV requires ownership, but text is misleading user as if reowning TPM)
- We should cache input, feed tpm behind the scene and wipe passphrase and state clearly that this is TPM disk unlock kye passphrase.
- primary key from TPM2 is invalid most of the time from kexec-select-boot and verifying global hashes but is setuped correctly at disk unlock key setup
- would be nice to take advantage of bash function tracing to understand where we are for debugging purposes, code takes ash in consideration only
- tpmr says it implements nv calls but actually doesn't. Removing those falsely wrapped functions would help.
- Implementing them would be better
- REVIEW TODOS IN CODE
- READD CIRCLECI CONFIG
Current state:
- TPM unseal works without disk unlock key and generates TOTP properly (was missing die condition at unseal to not produce always good TOTP even if invalid)
- TPM disk encryption key fails. Hypothesis is that sealing with USB drivers loaded and measures in inconsistent with sealed with/without.
- TPM disk unsealing happens without USB modules being loaded in non-HOTP setup. This fails.
- Current tests are with fbwhiptail (no clear called so having traces on command line of what happens)
- Testing with HOTP implementation for sealing/unsealing since that forces USB module loads on each boot to remove this from failing possibilities
- Add 4.19 under modules/coreboot
- point all 4.13 boards to 4.19
- adapt x230 FHD/EDP patch under patches/coreboot-4.19/0001-x230-fhd-variant.patch (poked upstream to fix patch under https://review.coreboot.org/c/coreboot/+/28950)
- correct versioning info under .circleci/config/yml
- update module version, hash
- rename patch
- update config
Busybox 1.33.0 adds base32, which has been disabled in busybox.config

- Coreboot 4.13 patch from coreboot at patches/coreboot-4.13/0002-x230-fhd-variant.patch

Otherwise binary patches cannot be patched/created
Additional fixes needed
- flashrom patch was invalid and got catched by git apply. Correcting
- gpg2-2.2.21.patch was pointing to bad target. Correcting
-Makefile: remove local gawk and make version compare and local build
-modules: remove gawk and make
-patches: remove make
local make was added to build 4.2.1 on OSes that were having older version. It was then patched to be built on OSes having newer buildstack.
local gawk was added when GPG toolstack was older then libgpg-error 1.37. GPG toolstack was then upgraded, but local gawk stayed.
Removing those permits better parallelization and of builds and reduces CircleCI (and higher cores systems) to have race conditions and stalled builds
- zlib 1.2.12 release is not respecting cross compiling. 1.2.11 disappeared from servers: taking another archive link, same hash.
- busybox 1.32.0 was not patched with 1.28.0 patch. Renaming patch so that its applied in fresh builds.
Heads build system is reextracting archives and reapplying patches on each iteration.
CircleCI optimizes building time by providing cache mechanisms and forces users to build a target under an hour.
This is to force Open Source projects (free tier) to not be leechers of the free tier.
In the past days, CircleCI bails on building coreboot 4.11 boards because some files being cached are already being present (created files from patches).
In those, two files were unwanted artifacts, recreated on top of coreboot 4.11 extracted original files (undesired .orig files), while bailing on the creating of src/security/tpm/sha1.c from patches/coreboot-4.11/0001-Add-Heads-TPM-measured-boot-support.patch.
Hopefully, this is CircleCI having a maximum of 3 automatically entered input (it fails on the 3rd)... And this fix will permit src/security/tpm/sha1.c and src/security/tpm/sha1.h to be skipped if existing.
Below, we see that CircleCI fills patch prompts with EOF 2 times, and then waits for input and then timeouts.
Here is the failing log trace from https://app.circleci.com/pipelines/github/tlaurion/heads/990/workflows/f2a430fd-dc8c-4e95-abe3-364a0e825533/jobs/4914/parallel-runs/0/steps/0-103:
