Configuration Table Use
=======================
sDeviceName
The name of this device.
deviceType
This field must be RTC_ICM7170.
pDeviceFns
The device interface control table. This must be icm7170_fns.
deviceProbe
This is the address of the routine which probes to see if the device
is present.
pDeviceParams
This field specifies the clock frequency. It may be one of the
following:
ICM7170_AT_32_KHZ
ICM7170_AT_1_MHZ
ICM7170_AT_2_MHZ
ICM7170_AT_4_MHZ
ulCtrlPort1
This field is the base address of the RTC area of the chip.
ulCtrlPort2
This field is ignored.
ulDataPort
This field is ignored.
getRegister
setRegister
These follow standard conventions.

General
=======
+ It would be nice to utilize the interrupt capabilities of some
RTC parts. This could be used to trigger checking the software
clock against the hardware clock.
+ The periodic capability of most RTCs is not suitable for use
as a general purpose flexible clock tick source. For example,
many RTCs generate only a handful of periods with 100 Hz being the
most frequent.
+ The tick field is not set on get. Anything smaller than a second
is ignored on set and get operations.
+ Day of week is ignored since RTEMS does not set it internally.
+ There is no attempt in RTEMS to know about time zones.
Harris ICM7170
==============
+ Untested.
+ Interrupt capabilities are ignored.
Mostek 48T08
============
+ Untested.
+ NVRAM is ignored.
