Modified files:
sys/i386/i386 nexus.c
Log:
Always create attach points for the various child busses that can be
attached to the nexus. With one exception, this (for example) allows
you to do wierd things like kldload the eisa bus on the fly and then
drivers, and have it auto probe the eisa bus when the drivers come online.
The one exception being pci, it only adds the pcib after the presence of
the pci bus is detected and that's #if'ed code.
A side effect of this is that isa and eisa will be attached to the nexus
directly rather than the PCI->ISA or PCI->EISA bridges. I'm not sure if
this is good or bad at this point, but it seems to be closer to the way
things are for the i386 family... This is likely to be followed up.
This also fixes compilation without a PCI bus configured and will allow
eisa to work without PCI too.
