Modified files:
sys/sys bus.h rman.h types.h
sys/kern subr_bus.c
Log:
Add two convenience functions for device drivers: bus_alloc_resources()
and bus_free_resources(). These functions take a list of resources
and handle them all in one go. A flag makes it possible to mark
a resource as optional.
A typical device driver can save 10-30 lines of code by using these.
Usage examples will follow RSN.
MFC: A good idea, eventually.
