That makes no sense to me. If you want to boot some OS, use a "boot*" commands, not "go" or the like.
i'm not talking about operating system code, i'm talking about flat binary applications that run bare metal. something like "u-boot.bin" where it's just a binary blob that gets loaded and u-boot jumps to it and never returns. since "go" isnt appropriate according to you (and seeing as how none of the> boot commands are appropriate), then the only next step is to implement a "jump" command that is exactly like "go" except it doesnt return.
This makes no sense. If it is ``exactly like "go"'' it doesn't matter if the code returns or not (and actually this is what I'm trying to point out all the time).
It's just that "go" shall retain the standard U-Boot environment for application it runs, and that the applications need to take care if they need to meddle with interrupts, exception handlers, etc.
