to look at the new patch set (#3).

nb/intel/haswell/peg: Add PEG driver stub
This is a port of https://review.coreboot.org/c/coreboot/+/22337 to the Haswell north bridge. This code is necessary to support the dGPU of the t440p. Code was cut and pasted from Sandybridge with vendor IDs updated to the correct Haswell values. Tested on t440p with dGPU on Ubuntu 18.04.4 with 5.3.0-29 kernel. Without patches dmesg reports Nouveau is unable to read the ROM of the dGPU as it has an invalid checksum (I checked that the ROM in CBFS is correct). With patches DRM appears to be initialized and dmesg only reports an error I assume is related to the Optimus setup of "DRM: Pointer to TMDS table invalid".
