i.mx6ull qspi nor flash boot mode

[strive]

Dear Expert:

How to change  i.mx6ull qspi nor flash boot mode,such as 2-wire or 4-wire?

What is the default qspi nor flash boot mode?

In the i.mx-rt reference manual:

It seems  nor-flash boot mode can change.

But in the i.mx6ull reference manual,there is not this content.

Please help ,thanks.
