For uncompressed Image, dtb is not necessary?
Just for clarification, dtb is optional for both vmlinux and Image
on arm64. (This means you can specify it if you want.)
But this is also true for initrd and append(command line) to some extent.
Yes, I agree.
More precisely, whether these parameters are optional or not will
depend on architectures, not formats, I believe.
May be not architecture, rather a distro environment.
For example, we should be able to work without --initrd for any arch if kernel
has been compiled by configuring CONFG_INITRAMFS_SOURCE.
