# 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.

# Make the Coreboot build depend on the following 3rd party blobs:
