When the components like LCM ID are not installed (i.e., NC), ADC will
return some value with much larger variation from standard value (out of
the tolerance we set). To support that, we should check tolerance only
on non-NC voltages.
Also improve the error messages so we can see the ADC raw values
instead of simple assertion error (which makes debugging more difficult
since we have to build another firmware image just to print the values).

Since there is no standardized naming scheme for the

As a workaround, add the option -n to SplitFspBin.py,

Previously Haswell used a romcc bootblock and starting verstage in
romstage was madatory but with C_ENVIRONMENT_BOOTBLOCK it is also
possible to have a separate verstage.
This selects using a separate verstage by default but still keeps the
option around to use verstage in romstage.
Also make sure mrc.bin is only added to the COREBOOT fmap region as it
requires to be run at a specific offset. This means that coreboot will
have to jump from a RW region to the RO region for that binary and
back to that RW region after that binary is done initializing the

'4074ce0cc7 (intel/apollolake: Add HDA to disable_dev function)'
FSP is now requested to switch off HDA PCI device if it is disabled in
devicetree. Doing so results in a warm restart. Normally this event
will be stored in CMOS RAM (if the descriptor is configured to do so)
and therefore no further resets are requested by FSP on the next boots
as long as CMOS RAM is kept alive.
The Siemens mainboards based on Apollo Lake do not have a CMOS battery
and therefore the CMOS is not backed up. This leads to reset requests
from FSP after PCI enumeration on every boot. To avoid this reset enable
HDA in devicetree for these mainboards. Though we do not have any usage
of HDA it should not be an issue that the HDA device is now enabled. The
benefit is though that no reset is requested anymore by FSP.
