Break out the detection logic for the aic7855 and properly report
these chips as 7855s instead of 7850s.
The 2940AU_CN is an aic7860 based card, not aic7860.
Not setting CACHETHEN turned out to be a bad idea. It can cause
spurious corruption under heavy PCI load with multiple masters.
the aic7890/91/96/97 cards. This could cause the system to go into
a long retry/recovery loop during probe.
Fix the alignment argument to bus_dma_tag_create().
Don't set the CACHETHEN bit in dscommand0 for Ultra2 controllers
until we know more about its behavior. The description for this
bit makes it sound like it could cause problems with certain
PCI chipsets.
only support 'mirroring' the vendor and device ids, so we don't
lose any information. Certain revisions of the aic7880 will not
perform the mirroring so to match all possiblities would double
the number of table entries. This change also allows us to match
things like the 2944B which I missed in the original table.
Sync up device Ids with the master Adaptec list.
Add probe support for the 2940 Pro although it isn't obvious that
all of the termination support is correct for this adapter yet.
Convert to new bus and bus dma.
Use latest PCI API.
bt_pci.c:
Fix a few bugs in how resourses are released left over from
when this driver was converted to new bus.
Recognize aic7895 controllers that have been "acquired" by a RAIDPort
card as normal aic7895s.
Recognize the aic7815 Raid Parity/Memory controller chip and notify
the user that it's RAID functionality will be ignored.
const char *. Originally I was going to add casts from const char * to
char * in some of the pci device drivers, but the reality is that the
pci device probes return constant quoted strings.
Disable DPARCKEN in the DSCOMMAND0 register on the aic7890/91/96/97.
Parity checking is broken for some chip/MB combinations and this
is the work around recommended by Adaptec.
dpt_pci.c:
Remove a superflous '{' that prevented DPT_ALLOW_MEMIO from working.
pcireg.h:
Add a definition for Parity Error Reponse bit in the PCI Space
command register.
