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.

2021-01-26cpu/intel/common/fsb.c: Add Broadwell CPUID modelsAngel Pons
Like Haswell, Broadwell has a "FSB" speed of 100 MHz. Add the IDs for both the traditional and ULT variants of Broadwell, because the CPU driver for Haswell already contains CPUIDs for both Broadwell types. Without this patch, Broadwell CPUs would hang when trying to print the first console log message, but only if flashconsole was not enabled. This was missed in commit f542b7bcef (cpu/intel/haswell: Add Broadwell CPUIDs and microcode) and went unnoticed until now because the tests were done with flashconsole enabled, which somehow boots properly even though the console time tracking would not work (depends on TSC). Tested on out-of-tree Acer E5-573, fixes booting without flashconsole.

Backport Broadwell's s0ix support to Haswell in preparation to unify both platforms' CPU code. Note that only ULT variants support s0ix. This option is currently unused, but will be put to use in subsequent commits, when switching Broadwell mainboards to use Haswell's CPU code. Tested with BUILD_TIMELESS=1, Asrock B85M Pro4 remains identical.

2021-01-21cpu/intel/socket_LGA775: Increase DCACHE_RAM_SIZEElyes HAOUAS
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.

Writing 0 to MSR IA32_BIOS_SIGN_ID before fetching this MSRs content is required. This is how things are done in cpu/intel/microcode/microcode.c. The "Intel® 64 and IA-32 Architectures Software Developer’s Manual" also recommends this: "It is recommended that this field be preloaded with 0 prior to executing CPUID" (this field being %edx).
