# Configuration for a X230 running Qubes 4.1 and other Linux Based OSes (through kexec)
#
# Based on https://review.coreboot.org/c/coreboot/+/28950 for FHD mod
# This has been reported to work with the following panels:
#        LP125WF2-SPB4 (1920*1080, 12.5")
#        LQ125T1JW02 (2560*1440, 12.5")
#        LQ133M1JW21 (1920*1080, 13.3")
#        LTN133HL10-201 (1920*1080, 13.3")
#        B133HAN04.6 (1920*1080, 13.3")
#        B133QAN02.0 (2560*1600, 13.3")
#
#    Other eDP panels not on this list should work as well.
#    Please verify if your panel needs a firmware mod.
#
# 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)

# 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 x230-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.
