[PATCH] ARM: mvebu: Add Netgear ReadyNAS 2120 board

[arno@natisbad.org (Arnaud Ebalard)]

All hardware parts of the (mv78230 Armada XP based) NETGEAR ReadyNAS
2120 are supported by mainline kernel (USB 3.0 and eSATA rear ports,
USB 2.0 front port, Gigabit controller and PHYs for the two rear ports,
serial port, LEDs, Buttons, 88SE9170 SATA controllers, three G762 fan
controllers, G751 temperature sensor) except for:

 - the Intersil ISL12057 I2C RTC Chip,
 - the Armada NAND controller.

Support for both of those is currently work in progress and does not
prevent boot.

Hi,

This one is intended for v3.14. This depends on the recent fix I pushed
for mv78230 PCIe and also on a small patch Guenter Roeck just accepted
to have lm75 driver support GMT G751 Temperature sensor (see 
https://lkml.org/lkml/2013/11/9/273).

Regarding the SATA presence and power pin definitions under pinctrl
node if you wonder, I thought it would not harm to have them for
reference even though they are currently not used. FWIW, I am currently
looking if a GPIO regulator can make any use of those.

Comments welcome,

Cheers,
