== QuadSPI NOR flash memory ==
=== Device tree configuration ===
This configuration work for Bora, Boralite and BoraX platforms.
Here below an example of device tree configuration used on standard DAVE's kit for the Bora, Boralite and BoraX ''QuadSPI NOR flash'':
From <code>bora.dtsi</code>:
<pre>
...
...
&qspi {
flash0: flash@0 {
// we need to use 128Mbit (16MiB) device compatibile even if
// the real hardware has a 256Mbit (32MiB) device because of
// Zynq QSPI controller limits
compatible = "spansion,s25fl128s1", "jedec,spi-nor";
#address-cells = <1>;
#size-cells = <1>;
reg = <0>;
spi-tx-bus-width = <1>;
spi-rx-bus-width = <4>;
spi-max-frequency = <25000000>;
};
};

</pre>
