arm: mvebu: add .dts file for Synology DS213j 



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)

 * The 0xf1000000 is the default used by the recent, DT-capable, U-Boot

 * bootloaders provided by Marvell. It is used in recent versions of

 * DSM software provided by Synology. Nonetheless, some earlier boards

 * were delivered with an older version of u-boot that left internal

 * 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.

 * by upgrading to latest version of DSM, or building a new one and

 * installing it from u-boot prompt) or adjust the Devive Tree

 * (s/0xf1000000/0xd0000000/ in 'ranges' below).
