Heads support for T480/T480s

[doritos4mlady]

Looks like a great candidate as it recently got libreboot support and is much faster than the T420/T430.

Is this something the devs would be interested in supporting?

The platform may be indeed attractive. I am not sure about being much faster. i7 3740qm/3840qm which can be installed on t420/t430 performs similar to i7 8550u. The newer CPU are less hungry though (45W vs 15 W). Both are EOL in terms of microcode updates. One issue for heads could be the TPM problem.
https://libreboot.org/docs/install/t480.html "The TPM is disabled on this device, to prevent hanging/boot delay in SeaBIOS, due to buggy TPM drivers there." Is this true only for SeaBIOS or for GRUB too?

Some discussion over Heads matrix channel thread on porting process for t480 if thread discussion is better for you to organize leadership of this port.

TPM works under coreboot but is "vulnerable to gpio reset attack" source

Would not be relevant to Heads in any case.

Any board owner here willing to take leadership into starting and leading the port?
