So, a long while back I asked about maybe adding a
"bootSOMETHING-THAT-GUESSES-YOUR-FORMAT" command to help here.  The
issue is that "bootz" means "boot an ARM Linux Kernel with the kernel's
decompressor that's at the front".  It's not even (sadly, arg) what
"boot an x86 Linux Kernel with the kernel's decompressor that's at the
front" is, that's zboot.  In the kernel (today), there's no desire to
add the decompressor "arm" has to "aarch64" and instead leave
decompression to the loader (And compression to the user).  So we have
to handle the Image format that aarch64 uses.

Frankly I've always looked at the distro work here as the
"boot-do-what-I-mean" stuff where we hide that the common multi-platform
image types aren't popular and just let people boot the "normal" kernel
for their architecture.
