     14     == QEMU Aarch64
     15 
     16     This target produces an image for the
     17     https://www.qemu.org/docs/master/system/arm/virt.html[QEMU "virt"
     18     platform] using a 64 bit CPU type.
     19 
     20     ARM targets differ from MIPS in that the kernel format expected by QEMU
     21     is an "Image" (raw binary file) rather than an ELF file, but this is
     22     taken care of by `+run.sh+`. Check the documentation for the `+qemu+`
     23     target for more information.
