kgpe-d16 linux configs: disable CONFIG_CRYPTO_AES_NI_INTEL (not avail on AMD)
This applied to Q35 qemu board which is AMD, not intel.
generic AES needs to be enabled on non-intel boards, otherwise cryptsetup doesn't know how to deal with xts-plain
Then saved back with linux.save_in_oldconfig_format_in_place
Enable the truncate coreutil.
CONFIG_BASE64 and CONFIG_BASH_IS_NONE just changed =n vs. not-set by
menuconfig, meaning is still the same.
initrd.cpio.xz went up by 512 bytes on Librem Mini v2 (probably the
minimum xz increment). busybox stripped binary did not change size.

Since legacy boards do not have e1000e as opposed to maximized builds (no network), we also deactivate:
+# CONFIG_INET is not set
+# CONFIG_ETHTOOL_NETLINK is not set
+# CONFIG_NETDEVICES is not set
This makes gpg24 and newer flashrom bump possible

CONFIG_CPU_ISOLATION=y : Enable CPU Isolation accross all boards: this permits to make sure that the kernel tasks running on a CPU are not distrurbed bu user tasks
CONFIG_MULTIUSER not defined: Removing cluttering since we are single root user under Heads anyway
CONFIG_IO_URING=y : limit number of copy operations between kernel and user space from apps
CONFIG_ZONE_DMA not defined: relevant for older hardware (less then 32bit addressing space)

It was impossible to use directly 4.14 defconfig and apply it to 5.10.
Saving 4.14 in oldconfig, then editing in 5.10 was necessary.
- E1000E module (as kernel module support...) was lost in conversion and needed to be added back.
Also tuned things up:
- legacy-flash has no RETPOLINE, no security policy at all. Has expected usb controllers modules, exFAT and bare minimal support for flashrom.
- IMPORTANT: CONFIG_X86_IOPL_IOPERM kernel option is required by flashrom
- legacy adds sata, retpoline, additional modules (ethernet), security policy related material on top of legacy-flash config
- maximized adds MMC card support, mousedev+synaptic (to report presence through oem-system-info-xx30), thin provisioning+snapshot support
- tuned with linux.prompt_for_new_config_options_for_kernel_version_bump
Current storage format is oldconfig from now on for proper analysis. If needed, once can save back in defconfig prior of bumping to newer version.

We don't need coreboot to initialize graphics on this boards, this
eliminates some unneeded code and the gnat dependency for them.
Coreboot was using libgfxinit, but it was initializing in text mode.
Heads' kernel will then switch to graphics mode, and we hand that
framebuffer from i915 to the target kernel during kexec.

Compressed framebuffer requires the driver to track updates to the
framebuffer from the CPU and update the compressed framebuffer. This
doesn't work if we kexec into an OS that will use the linear
framebuffer, so disable it. (The OS kernel can still use compressed
framebuffer if it has i915.)
Linux 5.8 enabled compressed framebuffer on more chipsets using i915,
which is why this stopped working.
memtest86+ and Debian (manually blacklisted i915, comparable to
netinst) now boot correctly on Librem 15v4. This will need to be
enabled for other boards too.

kexec(8) needs to get the framebuffer address in order to set up the
new kernel's boot parameters. This is one of the reasons that using a
>4.20 kernel in Heads prevents framebuffer graphics from working in the
OS kernel.
Linux 4.20 started hiding this address from userspace, because
userspace is not supposed to need physical memory addresses. A
workaround was added to keep leaking the address, apparently for some
proprietary userspace OpenGL drivers. This requires both a Kconfig and
a kernel parameter.
This commit enables the Kconfig on the librem_common config, and the
kernel parameter on the librem_15v4 (where I'm testing this). We will
need to enable it on other >4.20 configs/boards as well.

- Based on initial server board
- Uses whiptail as opposed to fbwhiptail (was slow and output fuzzy)
- Simple fix to have dual KVM(BMC) and vga output for consoles
Reasoning for dropping fbwhiptail support is that:
- it is impossible to output framebuffer content through remote BMC console.
- A workstation board config could output to fbwhiptail for VGA and give remote recovery shell access through BMC
- If someone shows interest for that, qemu-coreboot-tpm boards can be used as reference.
- slowness/fuzzyness of fbwhiptail output through AST would still need to be fixed in kernel drivers. Not a priority here.
Limitation:
- Since whiptail is sent to both consoles:
- If one console goes to recovery shell, recovery shell access invalidate TPM PCR4 measurements.
- The other console won't be aware that TPM measurements were invalidated, and will consequently:
- not be able to unseal TOTP if refreshed
- not be able to unseal TPM disk unlock key on default boot
- A reboot will fix this.
gui-init: do not consume two unseal attempt to unseal both totp and hotp + cosmetic changes (slow down TPM DA lockout)
kexec-seal-key: Add DEBUG statement for PCR precalc
seal-totp: add DEBUG statements regarding skipping of PCR5 and PCR6 involvement into TOTP/HOTP sealing ops
seal-hotpkey: Add DEBUG statements related to reuse of TOTP sealed secret
tpmr: add DO_WITH_DEBUG calls to output pcrread and extend calls
tpmr: typo correction stating TRACE calls for tpm2 where it was for tpm1
tpmr: add DO_WITH_DEBUG calls for calcfuturepcr
functions: Cosmetic fix on pause_recovery asking user to press Enter to go to recovery shell on host console when board defines CONFIG_BOOT_RECOVERY_SERIAL
Not so related but part of output review and corrections:
kexec-insert-key: cosmetic changes prepending "+++" to disk related changes
kexec-save-default: cosmetic changes prepending "+++" to disk related changes

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
- update module version, hash
- rename patch
- update config

I went through all of the different options we copied from the Librem
config. The only thing that stood out as irrelevant was NVMe support.
However, I'm not a Linux kernel expert, and I didn't do a deep dive, so
I'm sure there is still room for improvement.
Remove options that haven't deviated from defaults in the Coreboot
Kconfig, despite being saved by `make savedefconfig`. Also, add
`CONFIG_BOARD_LENOVO_THINKPAD_T440P`, which was missing from the `make
savedefconfig` output, causing Heads builds to fail. And finally, bump
`CONFIG_CBFS_SIZE` to `0x800000` (8 MiB to bytes to hexadecimal).
This value for the CBFS size is arbitrary. Originally, I had totaled the
size of all binary blobs, subtracted that from the T440p's ROM size (12
MiB), and used the remaining space as the CBFS size (~11.68 MiB).
However, this caused very long RAM initialization times (courtesy of
`cbmem -t`). And, an anecdote in
https://groups.google.com/a/chromium.org/g/chromium-os-reviews/c/lUqRrGUoEBY/m/ka7L1f2BS8gJ
suggested that this value needs to be a power of 2.
So, I picked a size I expected our Linux payload to fit into that was a
power of 2 that I also expected would leave enough space in the ROM for
the IFD, ME, GbE, and Coreboot.
Now, it takes less than a second for RAM initialization after
flashing/first boot (anecdotally, it seems the MRC needs to be
"trained?").
- ROOT_DISK_IMG is now dynamic (ROOT_DISK_IMG=/path/to/existing/provisioned/disk.img can be reused across run statements)
- Addition of missing boards to cover all use cases
- All TPM1 boards rely on common config/coreboot-qemu-tpm1.config
- boards/qemu-coreboot-fbwhiptail-tpm1-hotp/qemu-coreboot-fbwhiptail-tpm1-hotp.md has been generalized
- all other boards are softlinked to the above for usage
This makes configs much less dependent on directory layout.

Testing point:
- All board configs not explicitely stating export CONFIG_USB_KEYBOARD=y should not have any impact
- librem_l1um, kgpe-d16_workstation-usb_keyboard, librem_mini_v2 and librem_mini will loose USB Keyboard input with this commit alone.

Tested working. Fixes#1095
This commit adds explanatory notes and updates existing t530 and w530 boards to generally align them with the dGPU points and provide signposting for those with and those without dGPU boards. It also adds an additional README in the blobs directory to explain the vbios extraction and building process.
This commit adds support for the t530 and w530 boards to enable dGPUs. dGPU's are required for DisplayPort external displays in the t530 dgpu model, and for both the VGA dn DisplayPort external displays in the W530 (which has two dGPUs, the K1000M and K2000M, hence two boards). The commit does the following:
1. Adds automated extraction scripts for vbios modelled on the me script in the blobs directory (one per board is necessary as it is based on board-specific bios updates).
2. Adds specific boards for the various dGPU models and corresponding coreboot configs.
3. Updates circleci config.yaml to run scripts and test boards.
Tested and working on T530 dgpu and W530 K1000M. dGPU scripts tested on Debian 10 and Ubuntu 21.04
