Hi, Samuel. Are you using the development version or the stable version of gem5? I didn't check the stable version, but if you are using the development version there are files in "gem5/system/arm/simple_bootloader", which will let you make "boot_emm.arm" bootloader. Take a look at the Makefile in the directory I mentioned above.
