Log:
o Sync with the NetBSD mk48txx driver (the result simplyfies some changes
I have in mind for the genclock interface):
- Recognize the MK48T18 as well (differs from the MK48T08 only in
packaging options and voltages).
- Allow MD code to provide functions for reading/writing NVRAM/RTC
locations.
If passed NULL, the old behaviour using bus_space_{read,write}_1() is
used. Otherwise, all access to the chip goes via the MD functions.
This is necessary for mvmeppc boards where the mk48txx NVRAM/RTC is
not directly addressable.
- Cleanup MI mk48txx(4) todclock driver:
- Prepare mk48txxvar.h and leave only register definitions in
mk48txxreg.h.
- Define struct mk48txx_softc as usual devices and allocate necessary
members in it.
- Change mk48txx_attach() to only take a device_t.
o While converting the sparc64 eeprom driver to the above changes:
- Remove some dead code and stale comments.
- Use the NVRAM size provided by the mk48txx driver instead of hardcoding
it as suggested by a comment.
- Add a comment about why it doesn't make much sense to read the hostid
directly from the NVRAM except for displaying it when attaching.
- Don't print the hostid if it reads all zero because it's stored
elsewhere.
