Synology DS213j is a 2-bay NAS powered by a Marvell Armada 370
(88F6710 @1.2Ghz). It is very similar on many aspects to previous
2-bay synology models based on Marvell kirkwood SoC. Here is a
short summary of the device:
- 512MB RAM
- boot on SPI flash (64Mbit Micron N25Q064)
- 1 GbE interface (Armada MAC connected to a Marvell 88E1512
PHY via SGMII)
- 2 rear USB 2.0 ports (directly handled by the Armada 370)
- 2 internal SATA ports handled by the Armada 370: 2 GPIO for
presence, 2 for powering them
- two front amber LED (disk1, disk2) controlled by the SoC
- Seiko S-35390A I2C RTC chip
- UART0 providing serial console
- UART1 used for poweroff (connected to a TI MSP430F2111)
- Fan handled via 4 GPIO (3 for speed, 1 for alarm)

+ * registers mapped at 0xd0000000. If you have such a device you will
+ * not be able to directly boot a kernel based on this Device Tree. In
+ * that case, the preferred solution is to update your bootloader (e.g.
