The check is placed in the stub placement code. The stub placement
code is called twice. Once for the initial SMM relocatation and for

Add a function that initializes GPIOs based on the sleep type that
the system is coming back from. This allows initialization of the
fingerprint GPIOs which need to be handled differently between wake
from S3 and boot from S5.
On initial boot, the state of the FP sensor could be either
enabled or disabled. Because of this, on boot, we power off
the sensor for >200ms, to reset its state, then power it back on.
In suspend/resume, the fingerprint sensor should remain powered
the entire time.
If fingerprint is disabled on the trembyle-based board, set the pins
to no-connect. Dalboz doesn't have fingerprint and the GPIOS are
configured differently due to the FT5 chip having fewer GPIOS than
FP5, so nothing needs to be initialized there.
There were also a couple of trivial comment clean ups regarding the

Currently the decision of whether or not to use mrc_cache in recovery
mode is made within the individual platforms' drivers (ie: fsp2.0,
fsp1.1, etc.). As this is not platform specific, but uses common
vboot infrastructure, the code can be unified and moved into
mrc_cache. The conditions are as follows:
1. If HAS_RECOVERY_MRC_CACHE, use mrc_cache data (unless retrain
switch is true)
2. If !HAS_RECOVERY_MRC_CACHE && VBOOT_STARTS_IN_BOOTBLOCK, this
means that memory training will occur after verified boot,
meaning that mrc_cache will be filled with data from executing
RW code. So in this case, we never want to use the training
data in the mrc_cache for recovery mode.
3. If !HAS_RECOVERY_MRC_CACHE && VBOOT_STARTS_IN_ROMSTAGE, this
means that memory training happens before verfied boot, meaning
that the mrc_cache data is generated by RO code, so it is safe
to use for a recovery boot.
4. Any platform that does not use vboot should be unaffected.
Additionally, we have removed the
MRC_CLEAR_NORMAL_CACHE_ON_RECOVERY_RETRAIN config because the
mrc_cache driver takes care of invalidating the mrc_cache data for
normal mode. If the platform:
1. !HAS_RECOVERY_MRC_CACHE, always invalidate mrc_cache data
2. HAS_RECOVERY_MRC_CACHE, only invalidate if retrain switch is set
