2021-04-29cpu/x86/mtrr: Use a Kconfig for reserving MTRRs for OSTim Wawrzynczak
Some platforms which have large amounts of RAM and also write-combining regions may decide to drop the WC regions in favor of the default when preserving MTRRs for the OS. From a data safety perspective, this is safe to do, but if, say, the graphics framebuffer is the region that is changed from WC to UC/WB, then the performance of writing to the framebuffer will decrease dramatically. Modern OSes typically use Page Attribute Tables (PAT) to determine the cacheability on a page level and usually do not touch the MTRRs. Thus, it is believed to be safe to stop reserving MTRRs for the OS, in general; PentiumII is the exception here in that OSes that still support that may still require MTRRs to be available. In any case, if the OS wants to reprogram all of the MTRRs, it is of course still free to do so (after consulting the e820 table). BUG=b:185452338 TEST=Verify MTRR programming on a brya (where `sa_add_dram_resources` was faked to think it had 32 GiB of DRAM installed) and variable MTRR map includes a WC entry for the framebuffer (and all the RAM): MTRR: default type WB/UC MTRR counts: 13/9.

2021-03-19cpu/intel/fit: Add the FIT table as a separate CBFS fileArthur Heymans
With CBnT a digest needs to be made of the IBB, Initial BootBlock, in this case the bootblock. After that a pointer to the BPM, Boot Policy Manifest, containing the IBB digest needs to be added to the FIT table. If the fit table is inside the IBB, updating it with a pointer to the BPM, would make the digest invalid. The proper solution is to move the FIT table out of the bootblock. The FIT table itself does not need to be covered by the digest as it just contains pointers to structures that can by verified by the hardware itself, such as microcode and ACMs (Authenticated Code Modules).

2021-03-12cpu/intel/microcode: Fix caching logic in intel_microcode_findFurquan Shaikh
CB:49896 added support in `intel_microcode_find()` to cache the found microcode for faster subsequent accesses. This works okay when the function succeeds in finding the microcode on BSP. However, if for any reason, `cpu_microcode_blob.bin` does not contain a valid microcode for the given processor, then the logic ends up attempting to find microcode again and again every time it is called (because `ucode_updates` is set to NULL on failed find, thus retriggering the whole find sequence every time). This leads to a weird race condition when multiple APs are running in parallel and executing this function. A snippet of the issues observed in the scenario described above: ``` ... microcode: Update skipped, already up-to-date ... Microcode header corrupted! ... ``` 1. AP reports that microcode update is being skipped since the current version matches the version in CBFS (even though there is no matching microcode update in CBFS). 2. AP reports microcode header is corrupted because it thinks that the data size reported in the microcode is larger than the file read from CBFS. Above issues occur because each time an AP calls `intel_microcode_find()`, it might end up seeing some intermittent state of `ucode_updates` and taking incorrect action. This change fixes this race condition by separating the logic for finding microcode into an internal function `find_cbfs_microcode()` and maintaining the caching logic in `intel_microcode_find()` using a boolean flag `microcode_checked`. BUG=b:182232187 TEST=Verified that `intel_microcode_find()` no longer makes repeated attempts to find microcode from CBFS if it failed the first time.

Increase DCACHE_RAM_SIZE to 32kB and remove "NO_CBFS_MCACHE". It’s quite safe to increase DCACHE_RAM_SIZE. All LGA775 targets should have at least 256K L2 cache. That is plenty for XIP RO cache of bootblock + romstage and a 32K CAR.

2021-01-15cpu/x86/mpinit: Serialize microcode updates for HT threadsPatrick Rudolph
This change affects Intel CPUs only. As most platforms are doing uCode update using FIT, they aren't affected by this code either. Update microcode in MP-init using a single spinlock when running on a Hyper-Threading enabled CPU on pre FIT platforms. This will slow down the MP-init boot flow. Intel SDM and various BWGs specify to use a semaphore to update microcode on one thread per core on Hyper-Threading enabled CPUs. Due to this complex code would be necessary to determine the core #ID, initializing and picking the right semaphore out of CONFIG_MAX_CPUS / 2. Instead use the existing global spinlock already present in MPinit code. Assuming that only pre-FIT platforms with Hyper-Threading enabled and at most 8 threads will ever run into this condition, the boot delay is negligible. This change is a counterproposal to the previous published patch series being much more unsophisticated.

Target added to INTERMEDIATE all operate on coreboot.pre, each modifying the file in some way. When running them in parallel, coreboot.pre can be read from and written to in parallel which can corrupt the result. Add a function to create those rules that also adds existing INTERMEDIATE targets to enforce an order (as established by evaluation order of Makefile.inc files). While at it, also add the addition to the PHONY target so we don't forget it.

2021-01-11cpu/intel/haswell: Add delay for TPM before Flex Ratio rebootAngel Pons
Commit 542307b815 (broadwell: Add small delay before Flex Ratio reboot) introduced a workaround for Broadwell. Implement it on Haswell as well. Since this is only necessary when a TPM is present on a system, only do the delay (which is not that small, to be honest) on TPM-enabled builds.
