This commit adds two properties. One is used to set size of the low flash device and the other is used to select the low flash device. Then, the eSPI TAF request can access between two flash devices base on this setting. Signed-off-by: Tom Chang <CHChang19@nuvoton.com>

Properties defining the NPCX Quad-SPI peripheral of Flash Interface Unit (FIU).
|
|
A npcx quad-spi dt node would typically looks like:
|
|
|
|
&qspi_fiu0 {
|
|
status = "okay";
|
|
|
|
int_flash: w25q400@0 {
|
|
status = "okay";
|
|
reg = <0>;
|
|
...
|
|
};
|
|
|
|
ext_flash: w25q256@1 {
|
|
status = "okay";
|
|
reg = <1>;
|
|
...
|
|
};
|
|
};
|
|
|
|
`int_flash` and `ext_flash` are the devices accessed by this peripheral.
