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

# Configuration for a T530 running Qubes and other Linux Based OSes (through kexec)
|
|
#
|
|
# Includes
|
|
# - Deactivated+neutered ME and expanded consequent IFD BIOS regions
|
|
# - Forged 00:DE:AD:C0:FF:EE MAC address (if not extracting gbe.bin from backup with blobs/xx30/extract.sh)
|
|
# - Note that this MAC address can be modified under build/coreboot-VER/util/bincfg/gbe-82579LM.set
|
|
#
|
|
# - Includes Nitrokey/Librem Key HOTP Security dongle remote attestation (in addition to TOTP remote attestation through Qr Code)
|
|
# This board is designed for a t530 with a dGPU. Initialization of the dGPU is necessary in order to use an external monitor via the DisplayPort (either the in-built mini-DisplayPort or the DisplayPort in the dock). In order to build this the relevant script in the blobs directory must be run (or self-pulled roms placed in that directory) and after building the rom, the nvramtool must be run on the 12MB rom to change the default graphics mode away from integrated-only graphics (see README_vbios in the blobs directory).

# xx30-*-maximized boards require of you initially call one of the
|
|
# following to have gbe.bin ifd.bin and me.bin
|
|
# - blobs/xx30/download_clean_me.sh
|
|
# To download Lenovo original ME binary, neuter+deactivate ME, produce
|
|
# reduced IFD ME region and expanded BIOS IFD region.
|
|
# - blobs/xx30/extract.sh
|
|
# To extract from backuped 8M (bottom SPI) ME binary, GBE and IFD blobs.
|
|
#
|
|
# This board has two SPI flash chips, an 8 MB that holds the IFD,
|
|
# the ME image and part of the coreboot image, and a 4 MB one that
|
|
# has the rest of the coreboot and the reset vector.
|
|
#
|
|
# As a consequence, this replaces the need of having to flash t530-flash
|
|
# and expands available CBFS region (11.5Mb available CBFS space)
|
|
#
|
|
# When flashing via an external programmer it is easiest to have
|
|
# two separate files for these pieces.
