History
Warner Losh bc5676e30c RTC_TIMR's RTC_SEC field is BCD. That makes it unsuitable for 
GetSeconds().  Instead, use CRTR register shifted right 15.  This
gives us a range of 32 seconds we can do for timeout.

Shift to using == rather than < or > for calculating the timeout,
since if we can't read the ST_CTRT register twice in a second we have
even bigger problems to worry about, and == deals with the 'wrap'
issue.

This lets me type at the boot2 prompt again!  Woo Hoo!
