The amount of memory coreboot reserves for the FSP to use. In the
case of FSP 2.1 and newer that share the stack with coreboot instead
of having its own stack, this is the amount of anticipated heap usage
in CAR by FSP to setup HOB and needs to be the recommended value from
the Platform FSP integration guide. In the case of the FSP having its
own stack that will be placed in DRAM and not in CAR, this is the
amount of memory the FSP needs for its stack and heap.

The current FSP specification supports three notify phases:
- Post PCI enumeration

- End of Firmware
This option allows FSP to execute Notify Phase API (Post PCI enumeration).
SoC users can override this config to use coreboot native implementations
to perform the required lock down and chipset register configuration prior
to executing any 3rd-party code during PCI enumeration (i.e. Option ROM).
coreboot native implementation to skip FSP Notify Phase (Post PCI enumeration)
is still WIP.

Output FSP debug messages on serial console.
The config option is selected based on your FSP configuration i.e., debug or
release. Enable this option from site-local to print FSP serial messages using
coreboot native debug driver when coreboot has integrated the debug FSP
binaries. coreboot disables serial messages when this config is not enabled.
