+Subject: [PATCH 1/1] [WIP] OptiPlex 3050 Micro port
+
+- Boots Linux
+- SMSC SCH5553 SIO/EC
+ + Early EC init + HWM init implemented
+ + Console on serial port tested
+ + TODO: late HWM init for fan control (fan runs at low speed now)
+- 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
+- TODO: HDA verbs
+- TODO: USB ports
+- TODO: Add VBT
+- Currently limited to the Micro form factor, but others are very
+ similar
+
