freebsd/sys/dev/amr/amrreg.h
Eric Moore e8b5e74b61 amr.c, 
amr_cam.c,
amrreg.h,
amrvar.h:
- added support for 12/16 byte cdb's, effecting CAM branch only ( non-disk support )

amrreg.h:
- increased number of scatter gather elements from 16 to 26.

amr_pci.c:
- amr_pci_free(), incorrect bus tag meant for 'amr_mailbox_dmat' was being freed

all:
- copyright change requested by scottl

* We could actually use all 17 segments, but using only 16 means that

* maps crossing page boundaries.
*
* The AMI documentation says that the limit is 26. Unfortunately, there's no way to
* cleanly fit more than 16 entries in without a page boundary. But is this a concern,
* since we allocate the s/g maps contiguously anyway?
