Module Name:    src
Committed By:   tsutsui
Date:           Sun Mar 20 17:54:03 UTC 2011

Modified Files:
        src/sys/conf: files
        src/sys/dev/usb: files.usb

Log Message:
Add usb_dma attribute for DMA capable USB host controllers
and specify that usb_dma attribute to dev/usb/usb_mem.c.

usb_mem.c uses bus_dma(9) for DMA memory allocation,
but non-DMA capable USB host controllers like slhci(4)
doesn't need them at all, and some ports don't bother to
prepare MD bus_dma(9) implementation (yet).

Discussed on current-users
 http://mail-index.NetBSD.org/current-users/2011/03/13/msg015995.html
and usb_dma attribute is suggested by bouyer@.
Tested by kiyohara@ on mmeye with slhci at pcmcia.
