- 1GB DDR3 RAM
- MicroSD
- Gigabit Ethernet (RTL8211E)
- Wi-Fi 802.11b/g/n
- IR receiver
- Audio In/Out
- Video In/Out
- Serial Debug Port
- microUSB 5V 2A DC power-supply

Changes for v3:
- Fix to use mmc1 for SDIO instead of mmc2
- Replace buswidth by 4 instead of 8 mmc1
- Drop cap-mmc-hw-reset for mmc1
Changes for v2:
- Added ohci0, ehci0, ohic1, ehci1, usbphy.
- Tested on A64
