[PATCH v4 21/30] hw/isa/piix4: Remove unused inbound ISA interrupt lines
Posted by Bernhard Beschow 3 years, 1 month ago
The Malta board, which is the only user of PIIX4, doesn't connect to the
exported interrupt lines. PIIX3 doesn't expose such intterupt lines
either, so remove them for PIIX4 for simplicity and consistency.
