arm: imx: add iMX7D PICO MBL board definitionlinaro-pico
This patch adds an OP-TEE port for the i.MX7D PICO for the MBED Linux OS
boot flow.
BootROM -> ATF/BL2
ATF -> FIP {u-boot, OPTEE}
OPTEE -> {populates DTB overlay}
u-boot -> FIT {DTB, Kernel, initramfs}
Merges DTB and OPTEE DTB-overlay
Linux
CFG_NS_ENTRY_ADDR = 0x87800000 is the entry point of u-boot
CFG_DT_OVERLAY = y adds DTB overlay fragments to the passed DTB
make CROSS_COMPILE=arm-linux-gnueabihf- PLATFORM=imx \
PLATFORM_FLAVOR=mx7dpico_mbl ARCH=arm CFG_PAGEABLE_ADDR=0 \
CFG_TEE_CORE_NB_CORE=2
