I just want to remind you that we're applying for GSoC this year and for planning reasons they want us to state how many mentors we expect to have.
So if you're interested to potentially help a student get up to speed on a firmware related topic (coreboot or nearby projects), please reach out to me until Sunday, so I can finalize the paper work (which is due next week).
While students shall outline the project they want to work on in their application to GSoC, it's normal and expected to provide guidance in the form of project proposals. If you have ideas (and ideally are prepared to mentor students working on them) please reach out to me as well. I'll incorporate them in https://review.coreboot.org/c/coreboot/+/30972 so we'll have a maintained collection on our documentation site.
That list is also suitable for other situations but whatever the occasion, it always help to have a point of contact listed with any idea so that somebody interested in working on them knows who to contact for details and help.
