Sorry, I don't get it.  Why would we need separate global and local
timers?  And what exactly is "local" here - local to what?

We don't need anything like that on other architectures - so why here?

"general a good thing" sounds like "nice to have", and this is usually
something we don't really need, especially not in a boot loader.

Best regards,

Wolfgang Denk
