Instead of running StMM in SPM, OP-TEE creates a new secure partition, which emulates SPM and isolates StMM from the rest of the Trusted Applications (TAs). We can then compile StMM as an FD image and run it in OP-TEE. With the addition of a new RPMB driver, we can leverage OP-TEE and store variables to an RPMB device. Since EDK2 upper layers expect byte addressable code, for the RPMB to work, we need to allocate memory and sync it with the hardware on read/writes. Since DynamicPCDs are not supported in that context we can only use PatchablePCDs. So let's switch them to Pcd instead of FixedPcd and accomodate the new driver. While at it, move the rest of the variables under Pcd section, instead of FixedPcd -- this is in line with how the variables are defined in the other Variable modules.

# Provides SMM variable service.
|
|
#
|
|
# This module installs SMM variable protocol into SMM protocol database,
|
|
# which can be used by SMM driver, and installs SMM variable protocol
|
|
# into BS protocol database, which can be used to notify the SMM Runtime
|
|
# Dxe driver that the SMM variable service is ready.
|
|
# This module should be used with SMM Runtime DXE module together. The
|
|
# SMM Runtime DXE module would install variable arch protocol and variable
|
|
# write arch protocol based on SMM variable module.
|
|
#
|
|
# Caution: This module requires additional review when modified.
|
|
# This driver will have external input - variable data and communicate buffer in SMM mode.
|
|
# This external input must be validated carefully to avoid security issues such as
|
|
# buffer overflow or integer overflow.
|
|
# The whole SMM authentication variable design relies on the integrity of flash part and SMM.
|
|
# which is assumed to be protected by platform. All variable code and metadata in flash/SMM Memory
|
|
# may not be modified without authorization. If platform fails to protect these resources,
|
|
# the authentication service provided in this driver will be broken, and the behavior is undefined.
