New Revision: 203844
URL: http://svn.freebsd.org/changeset/base/203844
Log:
- Add the 'cmp' and 'core' pseudo-busses which are used to group CPU cores
to the exclusion lists as the CPU nodes aren't handled as regular devices
either. Also add the pseudo-devices found in Sun Fire V1280.
- Allow nexus_attach() and nexus_alloc_resource() to be used by drivers
derived from nexus(4) for subordinate busses.
- Don't add the zero-sized memory resources of glue devices to the resource
lists.
