CVS commit: src/sys/arch/i386/i386

[David Young <dyoung%netbsd.org@localhost>]

Module Name:    src
Committed By:   dyoung
Date:           Tue Apr  7 22:01:39 UTC 2009

Modified Files:
        src/sys/arch/i386/i386: mainbus.c

Log Message:
Let us re-attach acpi0, ipmi0, pnpbios0, and mca0 at mainbus0.

Extract code from mainbus_attach() to create a rescan hook,
mainbus_rescan().  Call mainbus_rescan(, "acpibus"/"ipmibus"/..., ) from
mainbus_attach() in the precise places where we used to attach acpi0,
ipmi0, pnpbios0, and mca0.  This allows, for example, ipmi0 to detach
and re-attach:

# drvctl -d ipmi0
ipmi0: detached
# drvctl -r -a ipmibus mainbus0
ipmi0 at mainbus0
#

Future work will let us detach & re-attach CPUs and the ISA/PCI/EISA
buses at mainbus0.
