as kernel little brother drivers are not needed anymore, the device numbers do not have to be correlated between kernel and uspace in any way
introduce new syscall sys_device_assign_devno() for generating system-wide unique device numbers for uspace |

Complete emancipation of kernel serial controller drivers (i8042, ns16550 and
z8530). Provide a common keyboard module for PC and Sun keyboards. The serial
line module is still to follow. |

Improve the ns16550 driver.
- The driver support multiple instances.
- It still remembers the last registered IRQ in a global structure (cannot be
easily fixed now)
- Was converted to use PIO directly |

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. |

Introduce a more platform-neutral name for programmed I/O.
The new API looks like pio_read_n() or pio_write_n(), where n is 8, 16 or 32.
The old API (i.e. inb(), inw(), inl(), outb() outw(), outl()) may have made
some people think that the interface is only to be used with the separate I/O
space. That's not the case. This API is to be implemented on all platforms
so that we can finally have really generic kernel device drivers. |

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. |

Move the new IRQ redirector to ddi/.

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. |

Convert sparc64 to detect keyboard and determine
its physical address by walking the memory representation
of the OpenFirmware device tree.
Add bus-specific functions that know how to apply the
"ranges" property to one component of the "reg" property.
Buses supported so far include FHC, EBUS and PCI. |
