The SMRR MSRs can be locked, so that a further write to them will cause
a #GP. This patch adds that functionality, but since the MSR is a
core-level register, it must only be done once per core; if the SoC has
hyperthreading enabled, then attempting to write the SMRR Lock bit on
the primary thread will cause a #GP when the secondary (sibling) thread
attempts to also write to this MSR.
BUG=b:164489598
TEST=Boot into OS, verify using `iotools rdmsr` that all threads have
the Lock bit set.

Fsp configures the USB over-current pin and overrides the according pad

Thus, set the OC pin to 0xff ("disabled") in this case to prevent this.
This allows us to skip setting USBx_PORT_EMPTY in the devicetree for
disabled USB ports.

typically obtained from part vendors but has to be massaged to format
it correctly as per JEDEC and MRC expectations. There have been
numerous times in the past where the SPD data used is not always
correct.
In order to reduce the manual effort of creating SPDs and generating
DRAM IDs, this change adds tools for generating SPD files for DDR4
memory used in memory down configurations on Intel Tiger Lake (TGL)
based platforms. These tools generate SPDs following JESD79-4C and
Jedec "4.1.2.L-5 R29 v103" specification.
Two tools are provided:
* gen_spd.go: Generates de-duplicated SPD files using a global memory
part list provided by the mainboard in JSON format. Additionally,
generates a SPD manifest file (in CSV format) with information about
what memory part from the global list uses which of the generated
SPD files.
* gen_part_id.go: Allocates DRAM strap IDs for different DDR4
memory parts used by the board. Takes as input list of memory parts
used by the board (with one memory part on each line) and the SPD
manifest file generated by gen_spd.go. Generates Makefile.inc for
integrating the generated SPD files in the coreboot build.

If there's already been an error and PSP_verstage is booting to RO,
don't reset the system. It may be that the error is fatal, but if the
system is stuck, don't intentionally force it into a reboot loop.
BUG=None
TEST=Force an error, still boots to RO instead of going into a boot loop
