Whiskey Lake (WHL)
Package/pin compatible Quad core WHL (U42) or Dual core CNL (U22) design in common board with stuffing option Two versions of CPU Si will be compatible with this platform:
• WHL U4+2 derived based on Coffelake-U with CNL-LP PCH
Use CFL-S/H code already in upstream(4.13-4.15)
PCI ID Changes: Graphics Related(v4.16)
• Cannonlake Prime –U 2+2 w/ CNL-H PCH and CNL-LP PCH
Use CNL-Y features (4.13-4.16)

Please don't forget CNL-H based components. Above is what I got from Intel.
