platform_get/set_rtc_time() is not implemented by any of the supported xtensa platforms. Remove the facility completely. The initial seconds for xtime come from read_persistent_clock() which returns just 0 in the generic implementation. Platforms that sport a persistent clock can implement this function. This is needed to implement the ccount as a clock source. Signed-off-by: Johannes Weiner <hannes@cmpxchg.org> Signed-off-by: Chris Zankel <chris@zankel.net>
