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
Blobs needed to build the Librem 13/15 boards are now
handled by the purism_blobs module; these scripts are
no longer needed.

- me_cleaner downloaded from 43612a630c/me_cleaner.py
- placed under xx30 blobs dir
- CircleCI uses it locally without downloading it everytime (me_cleaner hasn<t changed since 2018)
Ensure blobs end up in correct dirs, even when scripts are
called from the root project dir. Fixes issues when called
from CircleCI.

Incorrect parentheses brackets used in those scripts meant that the script as a whole did not return the correct exit code. The use of `( )` brackets created a sub-shell to which the exit code applied to that sub-shell. Changing to `{ }` does not create a sub-shell and as such, the script will return its true return code.
* 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).
Command returns a list of utilities found. This can happen if multiple
coreboot folders are present.
Use only one to fix a crash in the following lines.
Test: Being able to extract blobs when two coreboot folders are present,
both containing an IFDTOOL.

* 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.

- 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

* Add support for the Lenovo ThinkPad T420 and X220.
* Fix the autodetection of ifdtool and me_cleaner.
* Enable FBWhiptail mode for X220 and T420
* Decreased CBFS size to fix 50 seconds boot delay problems
Update hashes of coreboot images, releases repo, FSP blobs,

Rather than download large repositories of files from sources we
don't control and patch files as needed, simply extract the
files from precompiled, known good Purism coreboot images.
This offers multiple advantages:
- single source for all blobs, which we control
- significantly smaller download requirements for end user
- significantly less script complexity
- much, much faster

This links in the AcpiTableDxe and AcpiPlatform executables from
the edk2 build tree and adds a depex dependency for the Linux
kernel on the AcpiTable being setup. The `acpi.cpio` file is
no longer included in the Linux kernel bzImage.
The `Makefile.nerf` has been re-written to generate the firmware
file system (FFS) files via rules.
TODO: figure out how to add LZMA compressed sections so that the
900k acpi tables can be compressed to about 100k.
