If we do that we need to document what the new way of doing "just load and jump to the entry point of my not-a-linux-kernel ELF image" is; at the moment for ARM that use case is supported by -kernel (the code specifically handles ELF images as not-kernels), so changing that would be a back-compatibility break... (maybe this should be '-bios' but that seems a bit of an obscure name.) -- PMM
