-CircleCI addition.
-Removal of t530-flash, w530-flash boards, flash scripts and associated coreboot configs (no more legacy boards additions)
This is a merger of #1071, #1072 and #1073 so that test builds are available over CircleCI until osresearch/master CircleCI gets unlocked.
- xx30 legacy boards (x230, x230-flash, t430, t430-flash) now rely also on coreboot 4.13
- DOWNSIDE: x230 and t430 legacy boards now rely on WHIPTAIL (NOT FBWhiptail) to have enough space to fit under 7mb)
- xx20 boards moved to 4.13 (no need of xx20-flash boards here since single SPI boards with 7.5mb useable since blobs scripts are required)
- DOWNSIDE: all xx20 boards now have dropbear deactivated, while still having ethernet driver in.
- qemu-coreboot and qemu-coreboot-fbwhiptail switched to coreboot 4.13 WITHOUT TPM SUPPORT (with cryptsetup 2.x support)
- DOWNSIDE:
- coreboot-qemu board CBFS_SIZE=0x700000 -> 0x750000
- coreboot-qemu-fbwhiptail CBFS_SIZE=0x750000 -> 0x780000
- CircleCi build recipe removes 4.8.1 boards altogether
- KGPE-D16 workstation is used as new base build to save workspace layer (we removed one workspace layer)
- Removing one workspace layer will save approx 2 hours of build time on fresh builds
- Removing one coreboot version will save us approx 2 hours of build time on fresh builds
- KGPE-D16 will stay to coreboot 4.11 until forward notice.
- All other board configs SHOULD be built on latest coreboot versions
- all: coreboot NO_POST for all boards
- all: coreboot NO_GFX_INIT (linux payload does the graphic init)
- all: coreboot TPM_MEASURED_BOOT (no more patches under Heads for measured boot)
- all: coreboot DRIVERS_PS2_KEYBOARD (fixes no keyboard on soft reboot and potentially xx30t xx20t fix for random raw keyboard (to be tested)
- all: coreboot removal of DEFAULT_CONSOLE_LOGLEVEL_5 under some boards
- all: coreboot removal of "loglevel=3" under some linux command line options booting Heads kernel
- all: coreboot removal of DEBUG_SMM_RELOCATION (unneeded)
- all: coreboot INCLUDE_CONFIG_FILE and COLLECT_TIMESTAMPS for all boards
- all: coreboot CONSOLE_SERIAL present on all boards
- all: coreboot add VBT
- all: board configs switch to cryptsetup2
xx20 hotp-maximized boards:
- removal of dropbear (not enough space to have htop + dropbear)
txx0 boards coreboot:
- USE_OPTION_TABLE and STATIC_OPTION_TABLE added (todo: check T430 boards optimization and find issue/PR and ammend this commit)
We use 'iommu=igfx_off' for booting the Heads kernel, so use the same for
booting the OS to ensure consistency when kexecing

* xx30-*-maximized: update flashrom options removing --ifd bios option, keeping whole flash of rom internally. WARNING: ifd needs to be initially unlocked through ifdtool -u on 8mb bottom SPI backup. YOU CANNOT COME FROM 1VYRAIN. IF COMING FROM SKULLS, YOU MUST HAVE RAN OPTIONAL -u OPTION FROM SKULLS. PLEASE UPGRADE ONLY AFTER HAVING A PHYSICAL BACKUP OF BOTH SPI FLASH CHIPS. MORE INFORMATION UNDER https://github.com/osresearch/heads/pull/703. This will guarantee that future flash of produced rom will reflash the ROM totally, where heads make sure of adding users customizations (public key, /etc/config.user) when internally flashed. Unfortunately, if you flash externally, you will have to reinject your public key and readd /etc/config customizations.
* Adding generated bincfg coreboot 4.8.1 patch (merged under coreboot 4.13 and backported here to 4.8.1), resulting in gbe.bin under blobs/xx30/gbe.bin and instructions to replicate in README prior of automation (under repo). Note that MAC under gbe.bin is fixed to DE:AD:C0:FF:EE unless extract.sh script is ran on external backup to keep current user's MAC (Thanks to @Thrilleratplay's contribution!)
* xx30 blobs: add two blobs management scripts for xx30: extract from local backup/download+neuter ME
extract.sh: extract from external backup: gbe.bin, neuter under me.bin and maximize BIOS+reduce ME regions under unlocked ifd.bin.
download_clean_me.sh: download and verify Lenovo latest ME version from website, and drop me.bin in place.
Note: me.bin is 98kb, containing only BUP and ROMP partitions which cannot be modified nor deleted else computer won't boot. As a result, BIOS region is maximized in ifd.bin to 11.5mb and coreboot config takes advantage of that freed space.
* CircleCI: xx30-*-maximized additional step to call download_clean_me.sh prior of building boards so that me.bin is dopped in place. This should be done by users prior of building xx30-*-maximized boards locally, which is imitated in CircleCI builds (look at .circleci/config.yaml for innoextract host added dependency and board buildings. Results on github for each commit).

- "--max_old_space_size=4096" in CircleCI environement is supposed to limit memory consumption to 4096Mb of memory, the max of a medium class free tier CircleCI node
CircleCI: remove verbose build (no more V=1), in case of failed build, find all logs modified in last minute and output each of them on console.
coreboot module: implement load average respect inside of problematic CI build for coreboot 4.11+ being killed in the action (32 cores with 4Gb ram get gcc OOM)

This changes Heads' bootscript for the x230 to gui-init and adds config
options needed for it. The config is very similar to the librem13v2 config.
My comparison of startup-time from a power-button press shows 2.5 seconds
more with these changes applied.
That said, the experience is smooth, the GUI is beautiful and easier to use
than the shell and text menu, especially during setup. That's what we
buy with startup time here.
The Librem Key is a custom device USB-based security token Nitrokey is
producing for Purism and among other things it has custom firmware
created for use with Heads. In particular, when a board is configured
with CONFIG_LIBREMKEY, this custom firmware allows Heads to use the
sealed TOTP secret to also send an HOTP authentication to the Librem
Key. If the HOTP code is successful, the Librem Key will blink a green
LED, if unsuccessful it will blink red, thereby informing the user that
Heads has been tampered with without requiring them to use a phone to
validate the TOTP secret.
Heads will still use and show the TOTP secret, in case the user wants to
validate both codes (in case the Librem Key was lost or is no longer
trusted). It will also show the result of the HOTP verification (but not
the code itself), even though the user should trust only what the Librem
Key displays, so the user can confirm that both the device and Heads are
in sync. If HOTP is enabled, Heads will maintain a new TPM counter
separate from the Heads TPM counter that will increment each time HOTP
codes are checked.
This change also modifies the routines that update TOTP so that if
the Librem Key executables are present it will also update HOTP codes
and synchronize them with a Librem Key.
The bios regions of the 12M coreboot image is 7M: 4M and 3 of the 8M split
image. The rest of the 8M image _generated_ with fake data and not usable
on real systems! It's dangerous to create them and suggest flashing them
externally.
That's exactly why the x230-flash build target is there: To
have a self-contained 4M image and enable easy unlocking of the 8M image
using the _original_ data.
the heads-wiki project is updated accordingly.

Since fbwhiptail allows us to customize the background colors, we should
colorize warnings and error messages to provide a user with an
additional subtle cue that there might be a problem. I have added two
additional configuration options:
CONFIG_WARNING_BG_COLOR
CONFIG_ERROR_BG_COLOR
and in the librem13v2.config file you can see an example for how to set
them to be yellow and red gradients, respectively. I've also updated the
main two scripts that use whiptail to include those background colors.
If you decide to use regular whiptail, just don't set these config
options and it should behave as expected.
By enabling Pass-through iommu, it fixes the GPU glitching issues
