Userspace driver for OBIO. This will make it possible to clear interrupts from
user space on UltraSPARC IIi and systems with Psycho. Not tested. |

Unbreak sparc64.
Due to the lack of userspace bus drivers for the z8530 and ns16550,
we are currently handling exactly one interrupt from these devices
in userspace. |

IRQ handlers are using one superfluous argument and an unused elipsis.
On the other hand, IRQ claim functions would need to be passed the instance
argument. |

Add additional members to the irq_t structure so that an interrupt-driven driver
does not need to know how to clear the level interrupt. The z8530 was modified
in this way and is much more generic. The ns16550 driver has also been modified,
but awaits testing. The sparc64 interrupt mapping and dispatch code is now using
the new info and calls the clear-interrupt-routine itself. |

no spinlock can be held or the kernel will not be preemptive. This fixes Ticket #24.

register. The TICK register now increments linearily and can be used by the get_cycle()
function. |

Prototypical implementation of new IRQ redirector in sparc64.
The new code can support shared IRQs in kernel (and multiple IRQs per device).
Userspace support is yet to be written.
The only architecture that uses this code is actually sparc64 only. |

Add support for interrupt mapping in the Sabre PCI controller.
Add support for PCI and EBUS interrupt mapping via the OpenFirmware device tree.
Unfortunatelly, the code is not capable enough to earn single ns16550 interrupt.
I suspect something needs to be enabled in the EBUS registers. |

Extend the OFW device tree node with a void pointer. The boot loader is
supposed to reset all pointers in all nodes. The kernel uses the pointer
to recognize that a particular device has already been visited and initialized.
Read interrupt mapping from the OFW device tree for FHC devices (z8530) and
EBUS devices (ns16550). In case of FHC devices, remove hardwired values from
the code and use only values read from the tree. FHC initialization is started
when a FHC device wants to map its interrupt. In case of EBUS devices, map
the interrupt to INO. Interrupt enabling in the interrupt controller for that
specific interrupt is not implemented yet. |
