Again, thanks for this patch. Please, see my comments below.

The memory size is 256MB (0x10000000).

The serial clock-frequency is 166666667 for the net2big_v2 as well as
the TCLK frequency. It could smart to inherit the clock frequencies (if
not given) from the TCLK.

The regulator driver fails to register an already registred sysfs entry.
If I set "reg = <2>;" then the error goes away.

As for the d2net_v2, it would be nice to allow to enable/disable power
for the SATA disks.

This time, the memory size is OK :)

eth1 don't work and I don't know why. I can only say it works with the
legacy board-setup and Linux v3.10.

Before changing this options, we need to fix the Kconfig dependencies
for the driver led-netxbig. I will send a patch.
