> Provide hvc0 through the IKKAKU Open Firmware pseudo-console, validating
> model and console properties before matching. Serialize firmware calls,
> keep the bounce buffer in locked mappings and poll input each open tick.
>
> Keep output buffers const and bound no-progress retries because HVC
> retries EAGAIN indefinitely. A stalled firmware call remains unbounded.
> Use the existing SPARC p1275 interface and HVC output contract.
