T480-T480s Support

[compicat]

Hi, hope you are all well. Would you consider adding T480 and T480s support?

thanks for the question. I personally, though, don't really have an incentive for doing that. On that platform, it's mostly about Intel's bootguard being enabled and that it can be disabled. There are plenty of other laptops with much newer Intel processor platforms that have bootguard disabled and ship with coreboot in the first place, so that's no reason for me.

More importantly yet, for the platforms newer than Haswell, a coreboot build always needs Intel's "firmware support package" that can be of significant size. I personally won't run a coreboot "shell" around nonfree firmware.

A nicely configured T430 is not much slower than a T480 as well. But again, this is me personally. I'm very happy to include support, if it is in coreboot upstream (or soon) and somebody else commits to maintain it for the future.

@merge thanks for detailed and honest reply. Wish you best and thanks for amazing work again.

@merge I understand you are just giving your personal opinion, and are happy to include if someone does the work, but just to explain the appeal:

There are plenty of other laptops with much newer Intel processor platforms that have bootguard disabled and ship with coreboot in the first place, so that's no reason for me.

ThinkPad keyboard and InteME disable+neuter are not available with those newer laptops. Ability to neuter ends with Z370 in desktop (8th gen chipset replaced with Z390), and Kaby Lake S in laptop, due to management engine changes.

for the platforms newer than Haswell, a coreboot build always needs Intel's "firmware support package"

The FSP is indeed a significant drawback though.

A nicely configured T430 is not much slower than a T480

While quad-core Ivy Bridge benches are similar, quad-core Kaby Lake S works at much lower TDP, meaning power savings and considerably reduced weight of power brick and heatsink. It also has full h.265 decode/encode and decent integrated graphics compatible with Vulkan and modern stuff.

I'm very happy to include support, if it is in coreboot upstream (or soon) and somebody else commits to maintain it for the future.

Great!

Good night, people!
I found this by looking the Coreboot webpage.
If anything, recently I have bought a T480, and I wanna help.
