- Add locking. - Account for if the MC146818_NO_CENT_ADJUST flag is set we don't need to check wheter year < POSIX_BASE_YEAR. - Add some comments about mapping the day of week from the range the generic clock code uses to the range the chip uses and which I meant to add in the initial version. - Minor clean-up, use __func__ instead of hardcoded function names in error strings. o in the rtc(4) front-end additionally: - Don't leak resources in case mc146818_attach() fails. - Account for ebus(4) defaulting to SYS_RES_MEMORY for the memory resources since ebus.c rev. 1.22.

Add a driver back end for MC146818 and compatible clocks based on the

respective NetBSD driver for use with the genclock interface. It's first use will be on sparc64 but it was also tested on alpha with a preliminary patch to switch alpha to use the genclock code together with this driver instead of the respective code in alpha/alpha/clock.c and the rather MD mcclock(4). Using it on i386 and amd64 won't be that hard but some changes/extensions to improve the genclock code in general should be done first, e.g. add locking and make it easier to access the NVRAM usually coupled with RTCs.
