* 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.

As part of migration to coreboot 4.12, which includes measured boot
without additional patches, measure all parts of the firmware and the
payload into PCR2.
The same is done in coreboot 4.12. This commit ensures that boards not
migrated yet will show the same behaviour.

Update to nitrokey-hotp-verification master (c0956cf) and drop
existing patch which is no longer needed.
Test: clean build for Librem 13v2

Commit 7ea13ee0 made some significant changes to Librem/Nitrokey
verification which broke both compilation and calls to hotp_initialize.
Fix them via a patch until it's fixed upstream.

- 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

Modeled after modules/tpmtotp, use a specific git commit hash for
module libremkey-hotp-verification. Add hidapi as a submodule with
dummy/placeholder in modules (like coreboot-blobs), also specified
by git commit hash. Adjust libremkey-hotp-verification patch file
name so patch applied properly.

Fix HOTP verfication failure if LK admin pin/passphrase contains

Reading the file into a variable and then redirecting to stdin
via echo() can cause the binary data to be truncated, leading
to an invalid base32 value and failure to properly generate
and validate the HOTP code.
To resolve this, pass the file directly to hotp(), and ensure
it is removed properly regardless of success or failure to
prevent leakage.
Fixes "Invalid base32 string" error seen when attempting to
generate a new TOTP secret.

These two patches add the capability for coreboot to generate
the RMRR ACPI tables needed for proper IOMMU support. These
patches allow us to use 'intel_iommu=on' vs 'iommu=pt'

crossgcc is now using gcc 8.1.0 which will compile without issues
if your host system has gcc 8.x
This is required if we are to build on a new system (such as latest Fedora)
Currently the Librem Key tests will time out after 40 seconds, which
adds to the boot time significantly if the user wants to boot without
inserting it. This patch changes that timeout to one second.
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.
Fixes access to the EC through the Index I/O interface
Fixes AC and DC LoadLine values to avoid overheating problems
Fix Turbo mode value from EC
Change version name to have '-heads' suffix
Add a new series of patches which add measurement support for skylake,
add IOMMU for skylake, fix TPM support, and add support for TPM for
the Librem 13v2 and Librem 15v3 hardware.
This modifies the segment at 0x0 so that it contains enough of a fake
Extended BIOS Data Area at addresses 0x40e and 0x413 that Xen can
correctly locate its trampoline code.
Since custom Xen is no longer required, we can remove the module,
the patches and all of the references to it in the board definition
files.
This allows flashrom to work on the r630 NERF server, but
also increases the size of the flashrom executable significantly
since it brings in all chipset and flash types.
This development branch builds a NERF firmware for the Dell R630
server. It does not use coreboot; instead it branches directly
from the vendor's PEI core into Linux and the Heads runtime
that is setup to be run as an EFI executable.
Reduce the size of flashrom by commenting out most flash chips,
boards and programmers.
Wrapper script to make it easier to rewrite the ROM on the x230
using the flashrom layout.
Keep the entire 12 MB ROM for flashing.
Remove unused tools (crash kernel and vmcore).
Replace "%Lx" scanf formatting with "%"SCNxPTR in /proc/iommem
reading code. This might be a musl bug since it works with glibc
sscanf.
This resolves issue #73 by replacing the use of log10() with
an integer version so that -lm is no longer required.
The parts of dmsetup that we use don't need threads, so
-lpthreads is removed from the link line.
