We are trying to avoid that (direct reexports from the generated
bindings) - some explanations for how to abstract these follow.

This type should be wrapped in a transparent type similarly to e.g.
`GspArgumentsCached`: its internal structure hidden, and the needed
functionality made accessible through a constructor and (if needed)
other methods.

The opcodes can be exposed through a dedicated enum like `MsgFunction`.

These ones are a bit trickier to abstract. Since they ever only use
`bar` from the sequencer, I guess we can have their semantics in the
`fw` module, exposed through a method that receives the `bar`? That way
the sequencer won't have to access their members which are private to
it.

The sequencer does need access to the private fields, because the logic of what
to write to the bar should be in the sequencer, and that logic depends on the
fields.

Example:

impl GspSeqCmdRunner for fw::GSP_SEQ_BUF_PAYLOAD_REG_MODIFY {
    fn run(&self, sequencer: &GspSequencer<'_>) -> Result {
        let addr = self.addr as usize;
        if let Ok(temp) = sequencer.bar.try_read32(addr) {
            let _ = sequencer
                .bar
                .try_write32((temp & !self.mask) | self.val, addr);
        }
        Ok(())
    }
}

Here, the sequencer needs access to `.addr`, `.mask` and `.val` to craft the
address and the value to write.

I could expose access to those fields as functions, but I think we should not
move sequencer logic to fw.rs, that should live in the sequencer.

Or am I missing something? thanks,

 - Joel

Yeah although I floated the idea I have to admit I am not a big fan of
that either. So I guess we could have accessor functions for the fields,
so the `GspSeqCmdRunner` implementation stays in the sequencer?

It will at least provide the level of abstraction we require against the
firmware types' internal structure.

Yes, I will provide accessors for the fields for v4.
