Zaius has one flash module for the BMC firmware, one flash module for the host firmware, and one more flash module on SPI2.

I think we want to request the pins here. Something like this:

+
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_spi2ck_default

+                         &pinctrl_spi2cs0_default
+                         &pinctrl_spi2cs1_default
+                         &pinctrl_spi2miso_default
+                         &pinctrl_spi2mosi_default>;

+

Can you try that and do a test boot on your hardware?

Cheers,

Joel

Yes, we need this, though maybe the chip selects should be pushed out to the board dts?

Good catch! I hadn't picked up that the SPI2 flash wasn't being probed. Now it's showing up:
