I'm not sure. What exactly do you mean by "platform"?

Yes - that was a register dump of the init process, which is a
user-mode process.

You'd probably need to look this up in the ARM ARM. You'll need to
know the correct chip number of the ARM processor you're using, so you
can figure out which reference manual to use. The ARM ARM is either
