Hi,
In case the SPL on Gen5 loads U-Boot from NAND, unreset the NAND IP explicitly in the platform code as the denali-spl driver is not aware of DM at all.

Normal Denali Nand driver (denali_dt_probe()) is not running in SPL Gen5?
Nope, I tried to put the whole MTD subsystem into SPL, but it just does not fit into the 64 kiB we have on Gen5. It does fit on A10 which has 256 kiB of OCRAM, but I can't easily replace the SoC here. Hence this denali- spl.
Okay, now I understand your problem here.
I am enabling NAND for Agilex recently, but didn't notice need to de-assert
NAND reset outside of denali nand driver.
How much OCRAM does Agilex have again ? :-)
Agilex have 256KB OCRAM as in S10.
I wish I had that much OCRAM here too :)
