Due to Malta-specific board code forced into the PIIX4 reset values, Bernhard had to include an array of "register values at reset" as a class property. This is not wrong, but to model properly the model, we should simply use the hardware real reset values, not try to bend the model to please the Malta board. This series fix this issue by having the Malta bootloader code setting the board-specific PIIX4 IRQ routing values. Note patch 2 still misses an equivalent nanoMIPS code. Regards, Phil.
