T480/T480S: Support fetching ThunderBolt firmware Though not used in coreboot builds, and not injected into the builds in any way, these files are now created seperately when handling T480/T480s vendor files: vendorfiles/t480/tb.bin vendorfiles/t480s/tb.bin These are created by extracting Lenovo's ThunderBolt firmware from update files. The updated firmware fixes a bug; older firmware enabled debug commands that wrote logs to the TB controller's own flash IC, and it'd get full up with logs, bricking the controller. If you've already been screwed by this, you must flash externally, using a padded firmware from Lenovo's updates. Lenovo's own updater requires creating a boot CD or booting Windows. This patch in lbmk auto-downloads just the firmware, and you can flash it externally. You could simply do this as a matter of course, when installing Libreboot. You are recommended to update the Lenovo UEFI/EC firmwares first, before installing Libreboot; please look at the Libreboot documentation to know exactly which versions. Then dump the ThunderBolt firmware first, to be sure, and then you can flash these files. Flashing these updates will prevent the bug described here: https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t480-type-20l5-20l6/20l5/solutions/ht508988 You can download Lenovo's installers for various ThinkPad models there, including T480s/T480s. It is these downloads that this lbmk patch uses, to extract those files directly. Signed-off-by: Leah Rowe <leah@libreboot.org>
