# What works
 - Boots multi-user on [[!template id=man name="ld" section="4"]] @ [[!template id=man name="sdmmc" section="4"]] root and [[!template id=man name="com" section="4"]] console.
 - Ethernet ([[!template id=man name="cpsw" section="4" arch="evbarm"]])

# What needs work
 - EDMA3 (perhaps at first for [[!template id=man name="sdhc" section="4"]])
 - USB (host)
 - SPI
 - I²C
 - GPIO
 - Framebuffer/graphics with LCD or DVI/HDMI capes
 - Touchscreens on LCD capes
 - USB (device)
