Currently Heads will check files in /boot for tampering before booting
into a system. It would be nice if you could use the trusted environment
within Heads and extend this to check files in / itself. This new script
adds that functionality, however due to the length of time it takes to
perform these kinds of checks, it doesn't run automatically (yet).
This feature can be configured from the config GUI - the root device/
directories to check can be set, and it can be configured to run during
boot.
To make this a bit easier to use, I added a feature to detect whether
the hash file exists and if not, to display a more limited menu to the
user guiding them to create the initial hash file. Otherwise it will
display the date the file was last modified, which can be useful to
determine how stale it is.
Unify the CONFIG_BOOT_KERNEL_ADD/REOVE parameters for all
Librem boards. Ensure IOMMU disabled for the GPU, and that
duplicated IOMMU params are not passed to the kernel.

Update all Purism Librem boards except the L1UM server
to coreboot 4.15:
- update coreboot version from 4.8.1/4.13 to 4.15
- use purism_blobs module (if not already)
- update board coreboot defconfig files (Librem 13/15)

We use 'iommu=igfx_off' for booting the Heads kernel, so use the same for
booting the OS to ensure consistency when kexecing

Set and export currently-used defaults in gui-init, but still
allow for inidividual boards to override via config if desired.

This will allow it to be used elsewhere within the UI.
Rename CONFIG_BOOT_GUI_MENU_NAME to better indicate use/function.

* modules/linux: add support for building with kernel 5.4.69
Add support to module, port patches from 4.19.139.
Needed for newer platforms not supported by 4.19 kernel.

* Migrate all Librem boards to kernel 5.x, common config
Update linux-librem_common.config from 4.x to 5.x, and add
CONFIG items needed to support the librem_l1um (AST DRM drivers,
serial port output).
Tested on Librem 13v4, Librem Mini, and Librem Server L1UM.

There's only one Librem Mini board, it doesn't use a TPM,
no reason to unnecesarily lengthen the board name.

* CircleCI: readd librem_mini while making sure that if a board build fails, all logfile modified in the last minute are outputted on the CircleCI console prior to really failing and exiting
* librem_mini-NoTPM: addition of board config, distinctive coreboot config (required per Heads build system) to construct a ROM without TPM requirement.
* librem_mini: deletion of board and coreboot relative config, keeping librem_mini-NoTPM and coreboot config only. Removed librem_mini board build under CircleCI, keeping only librem_mini-NoTPM
* patches/coreboot-4.12: Add patch for Cannonlake ME status
Add patch print ME status regardless of enablement state

* modules: add purism-blobs module
Rather than require users to manually run a script to download the required
blobs to build Purism Librem boards, automate it so the correct version
is automatically downloaded/extracted. Restrict to coreboot 4.12 for now
since 4.8.1 still needs FSP blobs, which are not in module.
