This patch provides diagnostic information during the STM setup to
indicate when the MSEG is too small for what the STM requires.
The error message includes the configured MSEG size and the MSEG
area that the STM needs.

When a parallel SMM relocation is being done, there is a good chance
that the value for stm_resource_heap is not consistent across processors.
Rather than holding (via a lock) processors until this value is set and
then flushing the cache so that all processors see the same value, this
solution moves the code such that all processors set it, thus maintaining
parallelism and keeping the code simple.

This patch centralizes the MSEG location calculation. In the current
implementation, the calculation happens in smm_module_loader and
mp_init. When smm_module_loaderv2 was added, this calculation became
broken as the original calculation made assumptions based on perm_smbase.
The calculation is now located in smm_subregion (tseg_region.c), as the
MSEG is located within the TSEG (or SMM);
These patches have been tested on a Purism librem-l1um server.

Some platforms run the smm_relocation function twice during initialization.
This results in the BIOS resource list becoming twice as long. Also,
testing has shown that elements of the list created in the first interation
may have invalid data included in the resource list.
This patch resolves these issues by reseting the list every time stm_setup
is involked.

While the gcc(1) driver has the `-nostartfiles` option, ld(1), the
program the coreboot toolchain uses to link the object files, doesn't
have it.
In binutils before 2.36, this option is interpreted as `-n -o
startfiles`, in which the `-o` option is overridden by a later `-o`
option, so only the `-n` option has effect, which is the `--nmagic`
long option of ld(1). So the correct linker option in this place is
`--nmagic`.
It is tested that without `--nmagic`, ld can generate a much bigger
x86_64 romstage, so this option is still needed.
This error is found when trying to update binutils to 2.36 and later
versions, where ld(1) is unable to disambiguate options and reports an

Xeon-SP Skylake Scalable Processor can have 36 CPU threads (18 cores).
Current coreboot SMM is unable to handle more than ~32 CPU threads.
This patch introduces a version 2 of the SMM module loader which
addresses this problem. Having two versions of the SMM module loader
prevents any issues to current projects. Future Xeon-SP products will
be using this version of the SMM loader. Subsequent patches will
enable board specific functionality for Xeon-SP.
The reason for moving to version 2 is the state save area begins to
encroach upon the SMI handling code when more than 32 CPU threads are
in the system. This can cause system hangs, reboots, etc. The second
change is related to staggered entry points with simple near jumps. In
the current loader, near jumps will not work because the CPU is jumping
within the same code segment. In version 2, "far" address jumps are
necessary therefore protected mode must be enabled first. The SMM
layout and how the CPUs are staggered are documented in the code.
By making the modifications above, this allows the smm module loader to
expand easily as more CPU threads are added.
TEST=build for Tiogapass platform under OCP mainboard. Enable the
following in Kconfig.
select CPU_INTEL_COMMON_SMM
select SOC_INTEL_COMMON_BLOCK_SMM

Debug console will show all 36 cores relocated. Further tested by
generating SMI's to port 0xb2 using XDP/ITP HW debugger and ensured all
cores entering and exiting SMM properly. In addition, booted to Linux

Check to ensure that dual monitor mode is supported on the
current processor. Dual monitor mode is normally supported on
any Intel x86 processor that has VTx support. The STM is
a hypervisor that executes in SMM dual monitor mode. This
check should fail only in the rare case were dual monitor mode
is disabled. If the check fails, then the STM will not
be initialized by coreboot.

This update is a combination of all four of the patches so that the
commit can be done without breaking parts of coreboot. This possible
breakage is because of the cross-dependencies between the original
separate patches would cause failure because of data structure changes.
security/intel/stm
This directory contains the functions that check and move the STM to the
MSEG, create its page tables, and create the BIOS resource list.
The STM page tables is a six page region located in the MSEG and are
pointed to by the CR3 Offset field in the MSEG header. The initial
page tables will identity map all memory between 0-4G. The STM starts
in IA32e mode, which requires page tables to exist at startup.
The BIOS resource list defines the resources that the SMI Handler is
allowed to access. This includes the SMM memory area where the SMI
handler resides and other resources such as I/O devices. The STM uses
the BIOS resource list to restrict the SMI handler's accesses.
The BIOS resource list is currently located in the same area as the
SMI handler. This location is shown in the comment section before
smm_load_module in smm_module_loader.c
Note: The files within security/intel/stm come directly from their
Tianocore counterparts. Unnecessary code has been removed and the
remaining code has been converted to meet coreboot coding requirements.

Add TXT ramstage driver:
* Show startup errors
* Check for TXT reset
* Check for Secrets-in-memory
* Add assembly for GETSEC instruction
* Check platform state if GETSEC instruction is supported
* Configure TXT memory regions
* Lock TXT
* Protect TSEG using DMA protected regions
* Place SINIT ACM
* Print information about ACMs
Extend the `security_clear_dram_request()` function:
* Clear all DRAM if secrets are in memory
Add a config so that the code gets build-tested. Since BIOS and SINIT
ACM binaries are not available, use the STM binary as a placeholder.
Tested on OCP Wedge100s and Facebook Watson
* Able to enter a Measured Launch Environment using SINIT ACM and TBOOT
* Secrets in Memory bit is set on ungraceful shutdown
* Memory is cleared after ungraceful shutdown

Commit c1dc2d5e68 (mb/lenovo/t60: Switch to override tree) converted
these boards to override trees, but some device nodes were missed.
Said nodes are essential, as `chip` configuration data is always tied
to device nodes. The resulting `static.c` contained multiple copies
of the `chip` configuration structs, but the wrong ones were hooked up.
The therefore missing configuration of the clockgen led to general
instability, especially with SMP under Linux (probably due to the
attempt to enter lower C states on an idle core). Passing `maxcpus=1`
to the Linux kernel served as a workaround.
