CSE RW blob which will be used by coreboot to update CSE's RW partition,
is packed part of FW_MAIN_A and FW_MAIN_B. This will increase the size of
FW_MAIN_A and FW_MAIN_B. So, accordingly load and hash calculation of
FW_MAIN_A (or FW_MAIN_B) increases during verstage. It increases the boot
time by around 300ms.
The patch address the boot time by pulling CSE RW blob outside of
FW_MAIN_A and FW_MAIN_B. So, it creates new FMAP region within
RW_SECTION_A and RW_SECTION_B and adds CSE RW blob in the new regions
(ME_RW_A and ME_RW_B) as a CBFS file.
Boot Time Measurement details when CSE RW blob is added in the
ME_RW_A and ME_RW_B.
--------------------------------------------------------
| Platform | Old Boot Time | New Boot Time |
--------------------------------------------------------
| JSL | 1.3s | 1.06s |
--------------------------------------------------------
| TGL | 1.63s | 1.36s |
--------------------------------------------------------
Changes:
1. Makefile change to accommodate CSE RW blob into ME_RW_A/ME_RW_B
2. Kconfig change to define CBFS name and default file name for RW blob
metadata.
3. CSE Lite Driver

In the existing implementation CSE RW metadata file is generated by

* Move the metadata generation to the coreboot Makefile.
* Add CBFS component type struct to create a metadata file during
the compile time.
* Extract the CSE RW version from SOC_INTEL_CSE_RW_VERSION config
and update the major, minor, hotfix and build versions using the
compile time flags.
* Compute the hash of CSE RW binary in hex format using the openssl

mostly to increase readability: Nobody should have to wonder
if we're missing a NULL-check.
The condition is moved out of the loop to reduce indentation

Add a function that initializes GPIOs based on the sleep type that

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.
