Clément Léger	0c9fd82117	ARM: at91: add code to handle secure calls ... Since OP-TEE now has a more complete support for sama5d2, add necessary code to perform SMC calls. The detection of OP-TEE is based on a specific device-tree node path (/firmware/optee) such has done by some other SoC. A check is added to avoid doing SMC calls without having OP-TEE.
