 Binary Firmware Structure
 =========================
 
-At this point remoteproc only supports ELF32 firmware binaries. However,
+At this point remoteproc supports ELF32 and ELF64 firmware binaries. However,
 it is quite expected that other platforms/devices which we'd want to
 support with this framework will be based on different binary formats.
