Angel Pons uploaded patch set #2 to this change.
mb/asrock/h110m/romstage.c: Correct FSP-M UPDs
The DQ and DQS byte maps do not apply to DDR4 configurations, and the
RCOMP resistor and target values are not correct for SKL-S (or KBL-S).
Drop the byte maps and use RCOMP values for the correct platform type.
RCOMP resistor values for all non-socketed platforms are listed in the
Platform Design Guide, and also appear in schematics. For SKL-S, the
RCOMP resistors are on the CPU and their values have been confirmed
by measuring them on an i5-6400, and match the PDG values for SKL-H.
RCOMP target values can be guessed from Intel Document #573387 and some
of them are also present in datasheet volume 1, under DC specifications.
