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.
