| H A D | mk48txxvar.h | 137813 Wed Nov 17 12:54:12 MST 2004 marius 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. |
