imx8mq: add TEE support
TEE entry is defined as 0xFE000000. When there is SPD passed to makefile
, TEE_IMX8 will be defined.
Compiling OP-TEE support using "make PLAT=imx8mq bl31 SPD=opteed"
Note:
Since TEE image is located at DRAM 0xFE000000, so need to reserve
this space in UBoot and Kernel, by using gd->dram_size =
PHYS_SDRAM_SIZE - SZ_32M or else.
