From 65f868cac6f7fd5c3ad02046574c19f8f4673255 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Wed, 23 May 2018 14:17:25 +0200 Subject: Add _CPU_Counter_frequency() Add rtems_counter_frequency() API function. Use it to initialize the counter value converter via the new system initialization step (RTEMS_SYSINIT_CPU_COUNTER). This decouples the counter implementation and the counter converter. It avoids an unnecessary pull in of the 64-bit integer division from libgcc.
