Struct Winbond83977FloppySioDevice

pub struct Winbond83977FloppySioDevice<FDC: MaybeStubFloppyDiskController> { /* private fields */ }

Combo Floppy controller + SuperIO config controller, as specified by the Winbond W83977ATF SIO chipset.

DEVNOTE: This device simply aggregates multiple sub-devices into a single ChipsetDevice, accounting for weird quirks like overlapping port-io and shared interrupt lines.

Notably: this device contains no additional volatile state that needs to be saved/restored, outside of the state of its sub-devices.
