* Name: rx8010_rtc_initialize
|
|
*
|
|
* Description:
|
|
* Initialize the hardware RTC per the selected configuration.
|
|
* This function is called once during the OS initialization sequence by
|
|
* board-specific logic.
|
|
*
|
|
* After rx8010_rtc_initialize() is called, the OS function
|
|
* clock_synchronize() should also be called to synchronize the system
|
|
* timer to the hardware RTC. That operation is normally performed
|
|
* automatically by the system during clock initialization.
|
|
* However, when an external RTC is used, the board logic will need to
|
|
* explicitly re-synchronize the system timer to the RTC when the RTC
|
|
* becomes available.
|
|
*
|
|
* Input Parameters:
|
|
* None
|
|
*
|
|
* Returned Value:
|
|
* Zero (OK) on success; a negated errno on failure
|
|
*
