Subject: @dave_universetf: And so it goes that, even with Coreboot providing open firmware for x86, the very first instructions executed by the CPU come from proprietary blobs that do memory and chipset initialization :(

Subject: @dave_universetf: I'm told this is _a_ reason that the extremely early boot firmware for Intel (the FSP) and AMD (AGESA) is very closed source, because it contains stuff like high-speed bus training that reveal (to a trained eye) proprietary ASIC-level voodoo the fabs do.

Subject: @dave_universetf: So, you're twiddling properties of the transceivers to get a solid link, properties that are dependent on the specific way your specific manufacturer etched the circuitry onto the wafer. So it's, like, per-chip-process black magic you have to reinvent each time.
