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
 - Fan handled via 4 GPIO (3 for speed, 1 for alarm)

This v0 is just to gather initial comments. Some random notes and
questions (Andrew, Ben, Simon):

- Simon: why does fan_alarm_irq_handler in gpio-fan.c returns IRQ_NONE?

- When I bought the NAS, it had an old Marvell bootloader. After install
  of latest DSM version, the u-boot was a new one w/ I had to change the
  'ranges' in the .dts to the ones below to have the kernel boot. I guess
  new DS213j hardware will be shipped with new u-boot version at some
  point and this will be fine; Otherwise, users will either have to
  upgrade their DSM or manually s/1f/d0/ in .dts.

- Andrew,Ben: SPI flash partitions are correct, I can read all those,
  'file' recognize them and the content looks kosher. Nonetheless, I did
  a diff before and after a 'saveenv' under u-boot and u-boot
  environment is saved by u-boot itself in the middle of the kernel
  (0x40000 after the start of mtd1). This make kernel CRC incorrect and
  prevent u-boot to boot the kernel. If you have any idea on this, I am
  interested.

- Andrew, Ben: I did a single file for the .dts but I intend to create
  a .dtsi; I have started a .dts for the DS414 (2-core Armada XP) and
  they share various nodes.
