I'm not aware of a precise spec on this timing. Can you please provide more details of what constraints you're trying to satisfy?

Hi Brad,

I got feedback from my customer.
They would like to estimate the boot up time(until the Flash asserrring) from powering up their system. This is why they would like to know this time.
So, would you please provide me this data?

Best regards.

Brad is right. This timing depends on several factors, most importantly on boot device order. Therefore there is no specification for this timing. You or your customer can measure it on an EVM, to get a rough estimate.
