I am working on i.MX8MQ EVK. I want to know the boot flow sequence of i.MX8MQ like 

  • Where and who loads SPL and AFT images?
  • How the communication takes place between the SPL, ATF and the Uboot?
  • What are those Training test that are running on power on in SPL?
  • What does the file ddr_init.c and ddrphy_train.c do?(The file got after the DDR calibration)
