In OP-TEE, the "optee_core@" node is reserved, appended in non secure device tree (see mark_tzdram_as_reserved() function under CFG_DT) so this name must be checked in optee_get_reserved_memory(). We keep the check on /reserved-memory/optee@ node to have backward compatibility with STMT32Image booting, when the reserved node is already present in U-Boot or SPL device tree with name "optee@".
This patch solves a boot issue on board with OP-TEE for U-Boot compiled with stm32mp15_defconfig and without secure configuration device tree (stm32mp157c-dk2.dts for example).
