Thanks for logs, but these are for boot-loader and I don't think u-boot
consumes partition details.
could you share logs for kernel as well.

Thanks Anurag,
I think, you need qspi.phypattern under bootph-all, as I see u-boot
stage will/may do phy-tuning.
While at this, same thing needs to be cascaded to ospi flash as well.
