Hello build bot (Jenkins), Lijian Zhao, Nico Huber, Paul Menzel, Rizwan Qureshi, Subrata Banik, Aaron Durbin, Patrick Rudolph,
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/35739
to look at the new patch set (#6).
Change subject: [WIP]soc/intel/common/block: Update microcode serialized for HT threads ......................................................................
[WIP]soc/intel/common/block: Update microcode serialized for HT threads
On Hyper-Threading enabled platforms update the microcode on a core serialized for threads running on that core. This prevents the "microcode: Update failed" error seen in the console log on boards with multiple cores and Hyper-threading enabled.
The SDM and most of the BWG suggest doing this. Documented a few to get a common sense what should be done, when and how microcode should be updated.
TODO: * Fix MPinit's first microcode update * Remove comments that state microcode updates should be done after SMM setup (it should be done at end of MPinit) * Guard microcode updates on HT where required
