Subject: Re: [PATCH v2 6/6] hvc: add an M3000 firmware console backend

> Provide hvc0 through the M3000 Open Firmware pseudo-console, validating
> the firmware model and console endpoints before registering it. Keep
> firmware buffers in locked kernel mappings and serialize their use in
> atomic console contexts through the existing SPARC p1275 interface.
>
> Poll input while the TTY is open and synchronize close with timer
> rearming. Return zero on no progress so HVC retries buffered TTY output
> but drops stalled console chunks instead of spinning indefinitely.
> A firmware call that does not return remains unbounded.
