Presently, coreboot supports two instances of sending EOP cmd to
the Intel CSE.
1. Sending EOP cmd to CSE during `.final` operation from cse pci driver.
2. Starting with Alder Lake, the recommendation was to send EOP to CSE
earlier than CSE `.final` operation. Since then it's referred to as
`Sending EOP Early`. This method helped to save the CSE EOP
response time significantly.
During Meteor Lake platform, CSE EOP response time has become
non-deterministic and we have figured that sending EOP command later
than CSE .final operation is actually helping to optimize the boot time
significantly (around ~150ms savings compared to sending from `.final`
ops and ~5sec compared to sending CSE early).
Hence, this patch intended to create yet another kconfig for sending
CSE late (specifically after `.final` operation). The idea for this
newer config is to use the boot state machine for sending CSE EOP cmd.
The patch train in this series would add the specific changes to allow
sending EOP late and perform other essential operations required prior
booting to OS as coreboot decided to skip calling into FSP Notify phase.
Starting with Jasper Lake, coreboot sends EOP before loading payload
hence, this config is applicable for those platforms.
The current plan is that Intel Jasper Lake, Tiger Lake and Meteor Lake
platform will select this newer config from SoC code.
