Subject: [PATCH 4/8] mb/lenovo: Add ThinkPad T480 and ThinkPad T480s
These machine have BootGuard fused and requires deguard to boot coreboot.
Works:
- Intel GPU
- Internal screen
- Ethernet
- USB
- EC
+ Fan control
+ Keyboard
+ Battery (T480 has two)
+ Charging via both Type-C ports
+ Debug UART (on T480)
- WLAN card:
+ WiFi works
+ Bluetooth works
- M.2 main SSD
- HDA verbs, Speakers, headphone jack
- S3 sleep
Known issues:
- Alpine Ridge Thunderbolt 3 controller does not work
- Function keys are handled differently from stock firmware
+ These should inject XF86 keycodes instead of directly
controlling, volume, brightness, etc in hardware.
- Nvidia dGPU
- Needs option ROM
- Power enable code is buggy
- Nouveau only works on linux 6.8-6.9
Untested (should work):
- SATA main SSD
- WWAN slot
+ PCIe x2 NVME drive
+ WWAN card (bus)
- SD reader (USB)
- Webcam (USB)
- External video outputs
Thanks to Leah Rowe for helping with the T480s.
