2020-09-30security/intel/stm: Fix size_t printf format errorEugene D Myers
Size_t seems to have a compiler dependency. When building on the Purism librem 15v4, size_t is 'unsigned long'. In this instance, the compiler is the coreboot configured cross-compiler. In another instance, size_t is defined as 'unsigned short'. To get around the formatting conflict caused by this, The variable of type size_t was cast as 'unsigned int' in the format.

2020-08-07security/intel/txt: Fix variable MTRR handlingAngel Pons
The MSR macros were treated as memory addresses and the loops had off-by-one errors. This resulted in a CPU exception before GETSEC, and another exception after GETSEC (once the first exception was fixed). Tested on Asrock B85M Pro4, ACM complains about the missing TPM and resets the platform. When the `getsec` instruction is commented-out, the board is able to boot normally, without any exceptions nor corruption.

2020-02-05security/intel/stm: Add STM supportEugene Myers
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.
