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. -- Tom
