sys/sparc64/sparc64 tick.c
Log:
MFC: 1.15
UltraSparc II[e,i] based systems come up with the tick interrupt
enabled and a handler that resets the tick counter, causing DELAY()
to not work properly when used early in boot.
Disable the tick interrupt in tick_init(), which is called early in
sparc64_init(), until the interrupt is enabled again in tick_start(),
called by cpu_initclocks(), with our own handler. This fixes the hang
during probing Sun keyboards on AXi boards and Ultra 10, with other
machines like Ultra 5 probably being affected but not tested.
