"ACPI Error: [\_SB_.PCI0.LPCB] Namespace lookup failure, AE_NOT_FOUND (20160422/dswload-210)"
sounds like  the default path _SB.PCI0.LPCB does not match the actual path on the board?
e.g. in https://review.coreboot.org/#/c/18402/ I added the plumbing to make the path correct for AMD SB800 (for pcengines APU1).
This would probably need a similar patch for the affected board or alternatively make the default "_SB.PCI0.LPCB" configurable in Kconfig instead of hardcoded.
