IMX6UL Boot OP-TEE with NAND Flash

[kr90911]

Hi all,

I'm working on custom I.MX6UL board with 256MB NAND Flash, and I want to enable tee function on my board.

I read about this from i.MX_Porting_Guide.pdf:

Seems OP-TEE can only boot from SD card device.

Is there any way to boot OP-TEE with NAND Flash?
