Updated declarations of attach and probe functions.
Don't define dummy functions for un-supported bus space operations,
instead use the bs_notimp*() functions.
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.
the only timings we know are the ones inherited from the boot and the
drivers that will attach to the bus may change these.
Use the IS_PODULE macro for checking manufacturer and podule id's
against attach args.
sense code for zero and if found repeat the request sense. This solves
a bug in the sbic driver when accessing JAZ drives that results in
faulty sense data being returned following a transfer. A retry returns
the correct information.
This is probably showing up a more fundemental bug in the sbic driver
and will probably have to wait for a complete overhaul of the sbic
driver (planned) for a perfect fix.

shift value thus making register more flexible.
Remove the absolute shift of 2 in all the podule read/write routines and
use the tag cookie (passed in r0) as the shift value.
register shift value.
For the podulebus_bs_tag structure set the shift to 2 (the current
hardcoded value in the actual read/write routines).
Use the cookie to provide the register shift in podulebus_subregion().
they have different podule ID's.
Always attach the driver even if it appears to fail the tx test as there
appear to be a collection of cards around that will fail this tx test but
will actually work ok - This problem needs further investigation.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.
For the detailed change history, look at the commit log entries for
the is-newarp branch.
that a unit select did not complete and needs to be retried. Selection will
be retried following a disconnection if this flag is set. The function
esc_select_unit() will set/clear this flag depending on when a selection
completed or not.

podule space.
Fixed a bug in the reading of bytes from network slot cards that prevented
the correct reading of the network slot ROM description.
config code now allows duplicable devices to be attached.
a podulebus.
Make sure the podulebus driver conforms to the Acorn expansion card
specification:
- Probe the podule bus using sync access cycles rather than slow access
cycles.
- Read the podulebus header/ROM using sync access cycles rather than slow
access cycles
the AMD AM53CF94 Enhanced SCSI Controller. The code is based on the
SFAS216 driver as these chips are very similar. There are several
differences but more will follow.
Use definitions from this file for match_podule() rather than hardcoded
values.
Added a routine asc_minphys() in preparation for driver changes when on
card DMA support is added.
Use definitions from this file for match_podule() rather than hardcoded
values.
Reset the interface following a bad packet. This fixes some jams when
the driver failed to recover properly after a bad packet.
podule_data.h instead.
Removed the dead function find_podule().
The 0xf5 entry in the podules chunck directory is now searched for and
the podule description associated with this entry is placed in the
description field of the podule structure.
Generally tidied up all the comments.
multi-channel driver), or to SCSI_CHANNEL_ONLY_ONE if a
single-channel driver.
(2) use scsiprint() rather than a locally-defined autoconfig print
function, and kill any locally-defined print function.
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).
an extended header is present i.e. don't assume an extended header as
however unlikely there could be a podule that doesn't have one.
Calculate an absolute address for the podule's interrupt mask rather
than leaving it relative to the base address of the podule.
If the interrupt status pointers are not present or are zero then
used the default bits as specified in the podule specification to
determine if the podule is interrupting.
chained podule interrupt handlers.
Fill out the ih_maskaddr and ih_maskbits fields in the interrupt handler
structure so that interrupt dispatcher knows where to look to determine
if the handler should be called.
General code tidy up and source code formatting.

device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit. Updated interface to (*if_watchdog)() and (*if_start)()
to take a struct ifnet *, rather than a unit number.
matchpodule() is now used to test podule_attach_args for correct id's.
Moved the probing code that used the softc into the attach function.
Fixed compiler warnings generated with -Wall.
