From: Etienne Carriere etienne.carriere@st.com

Add boolean input argument @no_map to helper function fdtdec_add_reserved_memory() to add "no-map" property for an added reserved memory node. This is needed for example when the reserved memory relates to secure memory that the dear Linux kernel shall not even map unless what non-secure world speculative accesses of the CPU can violate the memory firmware configuration.

No function change. A later change will update to OPTEE library to add no-map property to OP-TEE reserved memory nodes.
