Hello Team,


     I have finished porting ddr3  from 512MiB to 1GiB successfully.I modified file "board/freescale/mx6ullevk/imximage.cfg" base on the parameters generated by  script "I.MX6ULL_DDR3_Script_Aid_V0.01.xlsx" and tool "ddr_stress_tester_v3.00". At the beginning,the board was unable to  start the kernel, and I try to comment uboot defconfig "CONFIG_IMX_OPTEE=y",it was able to start kernel normally.

    What I want to know is  what was the defconfig "CONFIG_IMX_OPTEE" used for and what  is the impact on the system when commenting the defconfig "CONFIG_IMX_OPTEE=y".


My develop environment:      




Thank you in advance.
