From 3a6550d989460f9449136814a8b1f6b051a6382d Mon Sep 17 00:00:00 2001 From: Stefan Reinauer Date: Thu, 1 Aug 2013 13:31:44 -0700 Subject: timestamps: Switch from tsc_t to uint64_t MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Cherry-pick from chromium and adjusted for added boards and changed directory layout for arch/arm. Timestamp implementation for ARMv7 Abstract the use of rdtsc() and make the timestamps uint64_t in the generic code. The ARM implementation uses the monotonic timer.
