This represents essentially a complete rewrite of the ISA PnP code. The new system is integrated with the ISA bus code more cleanly and allows the future addition of more enumerators such as PnPBIOS and ACPI. This commit also enables the new pcm driver since it is somewhat tied to the new PnP code.

Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL" is an application space macro and the applications are supposed to be free to use it as they please (but cannot). This is consistant with the other BSD's who made this change quite some time ago. More commits to come.

Newbus-ify the USR Sportster TA Intern driver. Enable the driver in sys/conf/files.i386. In isa/isavar.h increase ISA_NPORT from 32 to 50. This is required because this brain-damaged card maps 49 (!) port ranges. This does not have a negative impact because this value only specifies the maximum number of entries in a linked list and not the size of an array which is allocated in all drivers. The register/fifo access routines were not newbus-ified because 1) I knew that the old code worked and is simpler and more efficient 2) the if_ed driver does something similar and 3) the newbus macros collapse to inb/outb anyway.

* Add struct resource_list* argument to resource_list_alloc and resource_list_release. This removes the dependancy on the layout of ivars. * Move set_resource, get_resource and delete_resource from isa_if.m to bus_if.m. * Simplify driver code by providing wrappers to those methods: bus_set_resource(dev, type, rid, start, count); bus_get_resource(dev, type, rid, startp, countp); bus_get_resource_start(dev, type, rid); bus_get_resource_count(dev, type, rid); bus_delete_resource(dev, type, rid); * Delete isa_get_rsrc and use bus_get_resource_start instead. * Fix a stupid typo in isa_alloc_resource reported by Takahashi Yoshihiro <nyan@FreeBSD.org>. * Print a diagnostic message if we can't assign resources to a PnP device. * Change device_print_prettyname() so that it doesn't print "(no driver assigned)-1" for anonymous devices.

Sigh. Serves me right for testing against a modified tree (dfr's pnp changes). Doug changed these variables. This should fix the isa_compat.c breakage that phk reported. (Sorry!)

* Add hooks to allow the X server to access I/O ports and memory. * Update drivers to the latest version of the bus interface. The ISA drivers' use of the new resource api is minimal. Garrett has some much cleaner drivers which should be more easily shared between i386 and alpha. This has only been tested on cia based machines. It should work on lca and apecs but I might have broken something.

Bring the 'new-bus' to the i386. This extensively changes the way the i386 platform boots, it is no longer ISA-centric, and is fully dynamic. Most old drivers compile and run without modification via 'compatability shims' to enable a smoother transition. eisa, isapnp and pccard* are not yet using the new resource manager. Once fully converted, all drivers will be loadable, including PCI and ISA. (Some other changes appear to have snuck in, including a port of Soren's ATA driver to the Alpha. Soren, back this out if you need to.) This is a checkpoint of work-in-progress, but is quite functional. The bulk of the work was done over the last few years by Doug Rabson and Garrett Wollman.
