Information for you as a new member of the community:
The past 5 years intel (and AMD FM2/AM4) platforms are generally pretty locked down, it is very difficult to install blob free or even semi-open firmware replacement on them even if you could somehow get the documentation. (which they will never give a mere mortal like us) and the newer intel systems have something called "Boot Guard" which is a CPU enforced code signing mechanism to prohibit the installation of open source firmware entirely. You shouldn't buy intel if you want anything even somewhat libre friendly (at least AMD gives lip service to foss)

https://libreboot.org/ (more info on foss compat here, just ignore the politics)

Anyone who says they have a post 775/771 system that is 100% blob free open source is lying, that includes the purism scammers.
At this point for new systems you have select ARM and OpenPOWER systems (like the Raptor TALOS and the Tyan Palmetto, both HPC workstations/servers) I believe there are a few 100% FOSS laptops out there that aren't listed on the coreboot site but my age betrays me and I am forgetting what they are called. (I say again purism is a scam, do not buy from them.)

Does current coreboot master support my motherboard and laptop?

In wiki I can't find many braswell supported platforms and acer in vendor
