Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCI

command register. The lazy BAR allocation code in FreeBSD sometimes disables this bit when it detects a range conflict, and will re-enable it on demand when a driver allocates the BAR. Thus, the bit is no longer a reliable indication of capability, and should not be checked. This results in the elimination of a lot of code from drivers, and also gives the opportunity to simplify a lot of drivers to use a helper API to set the busmaster enable bit. This changes fixes some recent reports of disk controllers and their associated drives/enclosures disappearing during boot. Submitted by: jhb Reviewed by: jfv, marius, achadd, achim MFC after: 1 day

options DPT_HANDLE_TIMEOUTS hasn't worked since dpt(4) was converted to CAM

somewhere around svn r39402 to r39234. I don't know of anyone who really wants to test these changes, but they only remove the deprecated code in question. This shreds the driver down a bit and *removes* options from the kernel configs. These don't appear to be referenced in the man page, so no need to check it there.

Reform the busdma API so that new types may be added without modifying

every architecture's busdma_machdep.c. It is done by unifying the bus_dmamap_load_buffer() routines so that they may be called from MI code. The MD busdma is then given a chance to do any final processing in the complete() callback. The cam changes unify the bus_dmamap_load* handling in cam drivers. The arm and mips implementations are updated to track virtual addresses for sync(). Previously this was done in a type specific way. Now it is done in a generic way by recording the list of virtuals in the map.

Fix build of dpt(4).

- Use device_printf() and device_get_unit() instead of storing the unit number in the softc. - Remove use of explicit bus space handles and tags. - Remove the global dpt_softcs list and use devclass_get_device() instead. - Use pci_enable_busmaster() rather than frobbing the PCI command register directly.
