-Subject: [PATCH 1/5] mb/dell: OptiPlex 3050 Micro port (Intel KabyLake)
-
-- Boots Linux 6.11 (Debian)
-- GRUB and SeaBIOS payloads work
-- SMSC SCH5553 SIO/EC
- + Serial port works
- + PWM fan control works
-- Realtek Gigabit LAN works
-- WiFi slot works
-- NVMe SSD slot works
-- Extra: LPSS UART0
- + Stock FW sets undocumented power gating bit, RTC battery needs to
- be pulled for it to work.
- + Signals exposed on test points on the back of the board.
- FIXME: add documentation about this
-- Needs 'deguard' to bypass BootGuard
- + See https://review.coreboot.org/plugins/gitiles/deguard
-- Audio works
-- All USB ports work
-- Currently limited to the Micro form factor, but others are very
- similar
-- HDA verbs and VBT by Leah Rowe
-

+Subject: [PATCH 4/8] mb/lenovo: Add ThinkPad T480
+
+This machine has BootGuard fused and requires deguard to boot coreboot.
+
+Works:
+- Internal screen with VGA ROM executed by SeaBIOS
+- Intel iGPU
+- Nvidia dGPU (on some models)
+- Ethernet
+- USB
+- EC
+ + Fan control
+ + Keyboard
+ + Both batteries
+ + Charging via both Type-C ports
+ + Debug UART
+- WLAN card:
+ + WiFi works
+ + Bluetooth works
+- M.2 main SSD
+- Speakers, headphone jack
+- S3 sleep
+
+Known issues:
+- libgfxinit does not work
+- VGA ROM executed by coreboot does not work
+- Alpine Ridge Thunderbolt 3 controller does not work
+- Missing HDA verbs, audio still works
+- Missing VBT
+- Function keys are handled differently from stock firmware
+ + These should inject XF86 keycodes instead of directly
+ controlling, volume, brightness, etc in hardware.
+
+Untested (should work):
+- SATA main SSD
+- WWAN slot
+ + PCIe x2 NVME drive
+ + WWAN card (bus)
+- SD reader (USB)
+- Webcam (USB)
+- External video outputs

+
+too buggy, in mkukri's testing. just turn it off.
+
+thanks go to mkukri for showing me how to turn this off.
+as nicholas explained to me, if there's no nvram on this board,
+coreboot can't use a static option table, because that works by
+copying those settings to the nvram.
+
+so we just have to hardcode for the time being
