* Rewrite of puc(4). Significant changes are:marcel2006-04-281-104/+0
| | | | | | | | | | | | | | | | | | | | 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.

* - Introduce an ofw_bus kobj-interface for retrieving the OFW node and amarius2004-08-121-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | subset ("compatible", "device_type", "model" and "name") of the standard properties in drivers for devices on Open Firmware supported busses. The standard properties "reg", "interrupts" und "address" are not covered by this interface because they are only of interest in the respective bridge code. There's a remaining standard property "status" which is unclear how to support properly but which also isn't used in FreeBSD at present. This ofw_bus kobj-interface allows to replace the various (ebus_get_node(), ofw_pci_get_node(), etc.) and partially inconsistent (central_get_type() vs. sbus_get_device_type(), etc.) existing IVAR ones with a common one. This in turn allows to simplify and remove code-duplication in drivers for devices that can hang off of more than one OFW supported bus. - Convert the sparc64 Central, EBus, FHC, PCI and SBus bus drivers and the drivers for their children to use the ofw_bus kobj-interface. The IVAR- interfaces of the Central, EBus and FHC are entirely replaced by this. The PCI bus driver used its own kobj-interface and now also uses the ofw_bus one. The IVARs special to the SBus, e.g. for retrieving the burst size, remain. Beware: this causes an ABI-breakage for modules of drivers which used the IVAR-interfaces, i.e. esp(4), hme(4), isp(4) and uart(4), which need to be recompiled. The style-inconsistencies introduced in some of the bus drivers will be fixed by tmm@ in a generic clean-up of the respective drivers later (he requested to add the changes in the "new" style). - Convert the powerpc MacIO bus driver and the drivers for its children to use the ofw_bus kobj-interface. This invloves removing the IVARs related to the "reg" property which were unused and a leftover from the NetBSD origini of the code. There's no ABI-breakage caused by this because none of these driver are currently built as modules. There are other powerpc bus drivers which can be converted to the ofw_bus kobj-interface, e.g. the PCI bus driver, which should be done together with converting powerpc to use the OFW PCI code from sparc64. - Make the SBus and FHC front-end of zs(4) and the sparc64 eeprom(4) take advantage of the ofw_bus kobj-interface and simplify them a bit.

* Enhance puc(4) to support uart(4). This includes:marcel2003-09-061-0/+100
o Introduce PUC_PORT_TYPE_UART so that we can attach to uart(4), o Introduce port sub-types (eg PUC_PORT_UART_NS8250, PUC_PORT_UART_Z8530) to handle different hardware and determine resource sizes. o Introduce two new IVARs: PUC_IVAR_SUBTYPE and PUC_IVAR_REGSHFT. Both are used by uart(4) to get sufficient information to talk to the HW. o Introduce PUC_FLAGS_ALTRES to tell puc(4) to try memory mapped I/O if I/O port space cannot be allocated, or vice versa. o Have ports of type PUC_PORT_TYPE_COM attach to uart(1) if attaching to sio(4) fails (due to not having the sio driver). o Put struct puc_device_description in struct puc_softc instead of having a pointer to a device description in the softc. This allows us to create device descriptions on the fly without having to use malloc() or otherwise have them staticly defined. o Move puc_find_description() from puc.c to puc_pci.c as it's specific to PCI. o Add EBUS and SBUS frontends for use on sparc64. Note that the P in puc stands for PCI, so we kinda mess things up here. It's too soon to worry about it though. We'll know what to do about it in time. NOTE: This commit changes the behaviour of puc(4) to not quieten the device probe and attach for child devices. The uart(4) driver provides additional device description that is valuable to have.
