I am trying to boot my own "kernel" with qemu-microblaze but I can't

I tried the following cmdline:

none -s -S
img.elf: ELF 32-bit MSB executable, version 1 (SYSV), statically

How can I get the code of my elf to be emulated ?
I believe the "-kernel" option expects the file to be invoked
according to the conventions for invoking a Linux kernel. I
don't know what those conventions are for a microblaze, but
on most architectures, it involves something beyond a simple
ELF file.
As an alternative, you may want to look at options for loading
your kernel as a "ROM" firmware image, which would involve a
different set of conventions.
Enjoy
