+## Board status
+### Working
+- bootblock, romstage, ramstage
+- Serial console UART0, UART1
+- SPI flash console
+- iGPU init with libgfxinit
+- LAN1, LAN2
+- USB2, USB3
+- HDMI, DisplayPort
+- eMMC
+- flashing with flashrom externally
+
+### Work in progress
+- Documentation
+- ACPI
+
+### Not working / Known issues
+- Generally SeaBIOS works, but it can't find the CBFS region and therefore it can't load seavgabios. This is because of changes at the Apollolake platform.
+
+### Untested
+- GPIO pin header
+- 60 pin EXHAT
+- Camera interface
+ - MIPI-CSI2 2-lane (2MP)
+ - MIPI-CSI2 4-lane (8MP)
+- SATA3
+- USB3 OTG
+- embedded DisplayPort
+- M.2 slot
+- mini PCIe
+- flashing with flashrom internally using Linux
