+Trusted OS dispatcher
+=====================
+
+One can boot Trusted OS(OP-TEE OS, bl32 image) along side bl31 image on Allwinner A64.
+
+In order to include the 'opteed' dispatcher in the image, pass 'SPD=opteed' on the command line
+while compiling the bl31 image and make sure the loader (SPL) loads the Trusted OS binary to
+the beginning of DRAM (0x40000000).
