sorry for not noticing this before. Are these defines specific to the
Raspberry Pi, because of RPI?

I'm not entirely sure to be honest. It's the names that the register
have, but it's not clear to me if it's something specific to the RPi
itself, or it just means something else entirely.

My understanding is that this is a wrapper that was done specifically
for the Raspberry Pi usage of that IP block, which is why it has PI in
the name, so this looks good correct, and this does match the internal
register database name.
