How to enable power key long press boot sequence on i.MX6 ULL + evk board?

[alleenwang]

Hi guys,

We plan to use i.MX6 ULL and evk board for our product prototype.

MCIMX6ULL-EVK|i.MX6ULL Evaluation Kit|NXP 

Our product had 1 request was long press power key and boot-up device.

But, when we use i.MX6ULL and evk board, it will auto boot-up when connects the DC power.

Why evk board does not need to press the power key for device boot-up ?

How to enable this feature ? (Or re-work evk board ?)
