[linux-yocto] Adding SPI Flash in dtsi file.

[Pierre Lessard]

Hi,
I need to add the S25FL256SAGMFIR01 SPI Flash device to my recipe.
This is a 256MBit flash device.

I have a hard time figuring out what definition to add.

&ecspi2{
fsl,spi-num-chipselects = <1>;
cs-gpios = <&gpio5 29 0>; /* Native CS */
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_ecspi2_1 &pinctrl_ecspi2_cs_1>;
status = "okay";

my_flash: m25p256 at 0 {
compatible = "spansion,s25fl256s0";
spi-max-frequency = <10000000>;
reg = <0>;
mode = <0>;
#address-cells = <1>;
#size-cells = <1>;
partition at 0 {
label = "FPGA";
reg = <0x0 0x00A00000>;
};
partition at 0x00A00000{
label = "filesystem";
reg = <0x00A00000 0x01600000>;
};
};
};

Thanks,
