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

This config is a slightly stripped configuration of the Chromium OS
configuration used in production. Apparently the bootblock fills up
faster than usual on this device, resulting in address overflows.
Add this config here so we'll notice early in the future.

To avoid mangled characters on serial output from iPXE we have to disable
serial from iPXE console. More to that to have correct serial input we
have to enable SeaBIOS SERCON option with default configuration.
The only limitation of this configs is that apu5 doesn't detect iPXE -
that platform is not for public use so it doesn't affect anyone.

Rename `FRAMEBUFFER_KEEP_VESA_MODE` to `LINEAR_FRAMEBUFFER` and put
it together with new `VGA_TEXT_FRAMEBUFFER` into a choice. There are
two versions of `LINEAR_FRAMEBUFFER` that differ only in the prompt
and help text (one for `HAVE_VBE_LINEAR_FRAMEBUFFER` and one for
`HAVE_LINEAR_FRAMEBUFFER`). Due to `kconfig_lint` we have to model
that with additional symbols.
