From 03a830aad1cdf4325781aa60566bebcf5aa57238 Mon Sep 17 00:00:00 2001

Subject: [PATCH 3/4] libpayload: Get current tick from high register in
generic timer
This fixes the generic timer driver to get the current tick from the
high register, so that comparison with the high count value (obtained
previously from the same register) has a chance to succeed.
