DRA744: DRA714, DRA74X boot mode config

Part Number: DRA744
Other Parts Discussed in Thread: DRA714

Hello,

DRA714 &  DRA74X CPU want to boot by SD card, I want to know the system boot recognizing timing

  when the PMIC O917A148TRGZRQ1, O9039A38DIZWSRQ1) start to output. I connect the J6_3V3 output

from the CPU, it's to late to recognize the boot mode config.
