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.

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.

2021-01-14build system: Structure and serialize INTERMEDIATEPatrick Georgi
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.
