2020-10-22sec/intel/txt: Split MTRR setup ASM code into a macroAngel Pons
If necessary, SCLEAN needs to run in early romstage, where DRAM is not working yet. In fact, that the DRAM isn't working is the reason to run SCLEAN in the first place. Before running GETSEC, CAR needs to be torn down, as MTRRs have to be reprogrammed to cache the BIOS ACM. Further, running SCLEAN leaves the system in an undefined state, where the only sane thing to do is reset the platform. Thus, invoking SCLEAN requires specific assembly prologue and epilogue sections before and after MTRR setup, and neither DRAM nor CAR may be relied upon for the MTRR setup. In order to handle this without duplicating the MTRR setup code, place it in a macro on a separate file. This needs to be a macro because the call and return instructions rely on the stack being usable, and it is not the case for SCLEAN. The MTRR code clobbers many registers, but no other choice remains when the registers cannot be saved anywhere else. Tested on Asrock B85M Pro4, BIOS ACM can still be launched.

2020-10-22nb/intel/haswell: Add HASWELL_HIDE_PEG_FROM_MRC optionAngel Pons
The MRC will perform PCI enumeration, and if it detects a VGA device in a PEG slot, it will disable the IGD and not reserve any memory for it. Since the memory map is locked by the time MRC finishes, the IGD can not be enabled afterwards. Changing this behavior requires patching the MRC. Hiding the PEG devices from MRC allows the IGD to be used even when a dedicated graphics card is present. However, MRC will not program the PEG AFE settings as it should, which can cause stability problems at higher PCIe link speeds. Thus, restrict this workaround to only run when the HASWELL_HIDE_PEG_FROM_MRC option is enabled. This allows the IGD to be disabled and the PEG AFE settings to be programmed when a dedicated graphics card is to be enabled, which results in increased stability. The most ideal way to fix this problem for good is to implement native platform init. Native init is necessary to make Nvidia Optimus usable. Tested on Asrock B85M Pro4, using the PEG slot with a dedicated graphics card as well as without. Graphics in both situations function properly.

LockConfig only exists on Intel TXT for Servers. Check whether this is supported using GETSEC[PARAMETERS]. This eliminates a spurious error for Client TXT platforms such as Haswell, and is a no-op on TXT for Servers.

2020-10-22sec/intel/txt: Always run SCHECK on regular bootsAngel Pons
When Boot Guard is disabled or not available, the IBB might not even exist. This is the case on traditional (non-ULT) Haswell, for example. Leave the S3 resume check as-is for now. Skylake and newer may need to run SCHECK on resume as well, but I lack the hardware to test this on.

2020-10-22sec/intel/txt: Allow skipping ACM NOP functionAngel Pons
This is merely used to test whether the BIOS ACM calling code is working properly. There's no need to do this on production platforms. Testing on Haswell showed that running this NOP function breaks S3 resume with TXT. Add a Kconfig bool to control whether the NOP function is to be invoked.

2020-10-22sec/intel/txt/ramstage.c: Do not init the heap on S3 resumeAngel Pons
It causes problems on Haswell: SINIT detects that the heap tables differ in size, and then issues a Class Code 9, Major Error Code 1 TXT reset.

2020-10-22sec/intel/txt/ramstage.c: Extract heap init into a functionAngel Pons
Heap initialization is self-contained, so place it into a separate function. Also, do it after the MSEG registers have been written, so that all register writes are grouped together. This has no impact.

2020-10-22sec/intel/txt/common.c: Only log ACM error on failureAngel Pons
The TXT_BIOSACM_ERRORCODE register is only valid if TXT_SPAD bit 62 is set, or if CBnT is supported and bit 61 is set. Moreover, this is only applicable to LT-SX (i.e. platforms supporting Intel TXT for Servers). This allows TXT to work on client platforms, where these registers are regular scratchpads and are not necessarily written to by the BIOS ACM.

2020-10-22configs: Add TXT-enabled config for Asrock B85M Pro4Angel Pons
This config selects the necessary options to enable Intel TXT on the Asrock B85M Pro4, and allows the code to be build-tested. Note that the current TXT code will not work, as it was written for Broadwell-DE. Subsequent commits will adapt the code as necessary to work on Haswell. Compatible BIOS and SINIT ACMs can be retrieved from a firmware update for the Supermicro X10SLH. As they are not in the blobs repository, use the STM binary as a placeholder so as to allow build-testing the code.
