- Update flashrom module to v1.2.
- Drop Thinkpad x220 patch as it's now properly supported.
- Drop 'laptop=force_I_want_a_brick' from board FLASHROM_OPTIONS
since it's no longer needed.
- Migrate kgpe-d16 patch.
The kgpe-d16 patch needed a complete overhaul when rebased against
flashrom v1.2, and needs close inspection/testing as a result.
The following changes were made from the previous patch:
- dropped addition of 4-byte addressing (4BA), since now supported
- dropped addtiion of Macronix MX25L256 and MX66L512 chips,
since now supported
- added 4BA erase commands for Winbond W25Q256 chip
- dropped code to show progress indicator, since another PR already adds that

mount-usb switched to dynamic USB device detection a while back,
so eliminate instances of CONFIG_BOOT_USB_DEV, and derive the
mounted USB device from /etc/mtab in the one place where it's
actually needed (usb-scan). Clean up areas around calls to
mount-usb for clarity/readability.

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.
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
we've had with IOMMU, and it also allows us to boot a target kernel
without having to give it intel_iommu=igfx_off as argument.
