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.

structure so that interrupt dispatcher knows where to look to determine

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.
the podulebus attach function.
For each podule found, config_found_sm() is now called. Device drivers
now only need to look at the podule_attach_args information during
the probe.
A new function matchpodule() has been added for use in the
podule device driver probe functions.
- split softc size and match/attach out from cfdriver into
a new struct cfattach.
- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
memory test apparently causes hangups on some etherH interfaces.
Until this can be debugged with an offending interface the memory
test can be bypassed.
multiple packets were being received due to not flushing newly received
packets from the ring buffer between receiving an interupt and pulling
in the packets.
