Rewrite of puc(4). Significant changes are: o Properly use rman(9) to manage resources. This eliminates the need to puc-specific hacks to rman. It also allows devinfo(8) to be used to find out the specific assignment of resources to serial/parallel ports. o Compress the PCI device "database" by optimizing for the common case and to use a procedural interface to handle the exceptions. The procedural interface also generalizes the need to setup the hardware (program chipsets, program clock frequencies). o Eliminate the need for PUC_FASTINTR. Serdev devices are fast by default and non-serdev devices are handled by the bus. o Use the serdev I/F to collect interrupt status and to handle interrupts across ports in priority order. o Sync the PCI device configuration to include devices found in NetBSD and not yet merged to FreeBSD. o Add support for Quatech 2, 4 and 8 port UARTs. o Add support for a couple dozen Timedia serial cards as found in Linux.

Add MSI support to puc(9) Add support for MSI interrupts in the puc(9) driver. By default the driver will prefer MSI interrupts to legacy interrupts. A tunable, hw.puc.msi_disable, has been added to force the allocation of legacy interrupts. Reviewed by: jhb@ MFC after: 2 weeks Sponsored by: Sandvine Inc.
