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.
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
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.
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.
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.
