Hello, all. I've pushed my X201 work to gerrit. It also contains spkmodem and serialice improvements (target-side, like EHCI debug support). Host-side I attach a small patch to redirect clflush to target. Code quality is bad but it already works. Current known issues: speedstep doesn't work S3 doesn't work many ACPI buttons don't work.
You will also need following blobs: descriptor + me firmware VGA BIOS cpu microcode All are extractible from original BIOS by using the extract tool I published previously. cpu_microcode (UUID=3030435f-0000-0000-ff00-000000000000) has a range of ff...ff at the beginning you have to strip. VGA UUID is 3030525f-0000-0000-ff00-000000000000. descriptor and me firmware are files 001_descriptor.bin and 002_me.bin
