[PATCH 0/6] AT91 DT for 3.20 #1

[Alexandre Belloni]

This series enables RTC on the at91sam9n12 and at91rm9200.
It also adds nodes for the SRAM availabe on at91 SoCs.

Finally it adds a dtsi for the at91sam9xe and uses it for the ethernut5 dts.

Why here is 002fc000, while not 00300000? And length is on 0x4000.

I'll correct that one. I followed what was done before. The sam9260 has
two banks, one at 0x00200000, and the other one at 0x00300000. Thanks to
address mirroring on the range, we can declare that as one contiguous
range of sram, starting at 0x002ff000.

The same here, because we use mirroring, we have to disable the one that
is coming from at91sam9260.dtsi and then declare another one. I'll
correct the addresses in the reg properties. I was first declaring two
banks but we chose to switch back to only one range.
