[U-Boot] Disable command at runtime

[kubiznak.petr]

Hello,

I wonder whether it is possible to dynamically enable/disable a command. 
Since u-boot does not provide any secure authentication method, it is 
dangerous to keep some commands available to a potential hacker. E.g. 
the "fuse" command. On the other hand, I need these commands during the 
manufacturing process. So my idea is to enable/disable the commands 
dynamically based on some obscure logic. Is there a way to do it without 
need to deeply hack the code?

Thanks,

Petr
