Synology DS414 is a 4-bay NAS powered by a Marvell Armada XP
(mv78230 dual-core @1.33Ghz). It is very similar on many aspects
to previous 4-bay synology models based on Marvell kirkwood SoC.
Here is a short summary of the device:
- 1GB RAM
- Boot on SPI flash (64Mbit Micron N25Q064)
- 2 GbE interfaces (Armada MAC connected to two Marvell 88E1512
PHY via RGMII)
- 1 front USB 2.0 ports (directly handled by the Armada 370)
- 2 rear USB 3.0 ports (handled by an EtronTech EJ168A XHCI
controller on the PCIe bus)
- 4 internal SATA ports handled by a Marvell 88SX7042 SATA-II
controller on the PCIe bus)
- Seiko S-35390A I2C RTC chip
- UART0 providing serial console
- UART1 used for poweroff (connected to a Microchip PIC16F883)
Additional note: the front LEDs, the two fans and the buzzer are not
directly connected to the SoC and under its control. The former are
presumably driven by the SATA controller, the latter by the PIC.

+ * 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.
