common back-ends that live on multiple very-different busses (e.g. PCI and
TC), which need bus-specific DMA mapping support. As a nice side effect,
this will allow the especially nasty (vtophys(va) | 0x40000000) expressions
to go away in favor of less nasty bus-specific function calls.
from the current apecs_pci.c. This new version hopefully works for
the same sets of devices that that previous one did, and hopefully
will work for multi-function devices and for secondary PCI busses as
well. (looking at the code, there was no way the old one could have!)
- split softc size and match/attach out from cfdriver into
a new struct cfattach.
- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
Support for AXPpci CPUs,
Support for AlphaStation 600 CPUs,
new boot block structure, which requires an 'installboot'
program and works a lot like the NetBSD/sparc boot blocks.
Should be better integrated into autoconfig. Also, interface should
be designed rather than cobbled together... Nasty, but it Works.
needs things like ability to pass ioctl()s down to components, ability
to mmap() things, etc.
