PSR data is created and stored in CSE data partition. In platforms that
employ CSE Lite SKU firmware, a firmware downgrade involves clearing of
CSE data partition which results in PSR data being lost. In order to
backup PSR data before initiating firmware downgrade, CSE Lite firmware
supports a command to do this. This command works only after memory has
been initialized. So the CSE firmware downgrade can be done only in
post-RAM stage. CSE firmware sync actions will be moved to early
ramstage to support this.
Moving CSE firmware sync actions to ramstage results in cse_get_bp_info
command taking additional boot time of ~45-55ms. To avoid this,
cse_get_bp_info will be sent in early romstage and the response will be
stored in cbmem to avoid sending the command again, and re-use in
ramstage.
This patch adds a CBMEM ID to store this CSE Boot Partition Info
response in cbmem.

cse_store_rw_fw_version() stores CSE RW firmware version in global
variable or cbmem in romstage and ramstage respectively, based on the
stage it is called in. The call to this function is from the
cse_print_boot_partition_info() in cse_get_bp_info.
In the subsequent patches, the idea is to send the cse_get_bp_info early
in romstage and store in cbmem once memory is initialized. So when the
cse_fw_sync is called in early ramstage, the stored cse_bp_info_rsp is
used instead of sending the CSE get boot partition info command again.
To de-link the call to cse_store_rw_fw_version from cse_get_bp_info and
to ensure the CSE RW FW version is stored in all cases, moving the
function to do_cse_fw_sync.

PSR data is created and stored in CSE data partition. In platforms that
employ CSE Lite SKU firmware, a firmware downgrade involves clearing of
CSE data partition which results in PSR data being lost.
CSE Lite SKU firmware supports a command to backup PSR data before
initiating a firmware downgrade. PSR data backup command works only
after memory has been initialized. Moving only the downgrade would add
complexity of splitting the cse_fw_sync across pre-RAM and post-RAM
stages. So the idea is to move cse_fw_sync into ramstage when PSR is
enabled.
We are introducing a flow to get CSE boot partition info in early
romstage and then same data will be stored in cbmem once DRAM is
initialized. The CSE BP info data in cbmem will be utilized in early
ramstage to perform cse firmware sync operations. This helps in avoiding
re-sending the CSE get boot partition info command in ramstage. Having
cse_bp_info_rsp as global helps in de-linking cse_get_bp_info from
cse_fw_sync.
Many functions take cse_bp_info as input parameter. Since
cse_bp_info_rsp is global now, we can make use of global cse_bp_info and
remove it as input parameter from those functions.

Brya queries the TPM in early ramstage (pre-device init) to determine
if the CR50 has support for long-pulse interrupts. If the TPM (and
underlying I2C controller) hasn't already been setup in verstage, it
will fail to do so in ramstage since the I2C controller has not yet
been initialized. To work around this, initialize the TPM in bootblock
for the non-vboot case, to ensure the I2C controller is set up when
needed in early ramstage.

Intel Meteor Lake QS silicon provides better size optimized pre-x86
reset blobs.
This patch creates a new flash layout (FMD) for QS to accommodate those
optimizations, and renames the existing FMD for ES (pre-prod) silicon.
Comparative analysis between QS and ES flash layout is here:
For QS silicon:
- SI_ALL reduced from 9MB to 8MB.
- SI_BIOS increased by 1MB (from 23MB to 24MB) to fill in the 32MB SPI
layout.
- ME_RW_A/B reduce from ~4.5MB to 4MB.
- Ensure RW-B slot is starting at 16MB boundary.
- Unused space increased by 1MB.
For ES silicon:
- SI_ALL: 9MB
- SI_BIOS: 23MB
- ME_RWA/B: 4.5MB (for ISH) and 4.4MB (non-ISH).
- Unused space 3MB (for release) and 2MB (for debug) layout.

The options in conf.py for the following build targets are either
commented out or contain example values, which suggests that there was
no interest in them recently. Their comments also seem more like
generated examples.
* LaTeX
* man pages
* Texinfo
In order to clean up our configs and scripts for the documentation,
remove the configuration options from conf.py for these build targets.
Also, remove the build targets responsible for generating a PDF file
from Makefile. Don't touch Makefile.sphinx for now though as we usually
wrap around it.
We may bring these build targets back if there is real interest in
them, but it seems only the HTML target was really used.
