IMX6UL TCK Pull-Down

Hello,

Is the pull-down on JTAG_TCK for IMX6UL really mandatory.

1. EVK has a cpull-down on this signal

2. IMX6UL Hardware Development Guide on Table 16 (chapter 2.3) says it's not required.

This pull-down is a problem for me because I'm using this pin for another purpose where only a pull-up is allowed. What are the risks if I let only the internal pull-up during boot ?
