New Revision: 330767
URL: https://svnweb.freebsd.org/changeset/base/330767
Log:
Convert atrtc the new style rtc debugging output. Remove the db show
command handler which provided much the same information. Removing the
possibility of accessing the hardware regs from the debugger context
paves the way for simplifying the locking code in the driver.
