From 20d3d53433fa37eec5b573722f253c7f15d12c52 Mon Sep 17 00:00:00 2001 From: Vadim Bendebury Date: Thu, 1 May 2014 15:24:32 -0700 Subject: ipq8084: provide monotonic us timer MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This service is required by various coreboot code modules. It looks like the 8064 SOC does not provide anything better than a 32 KHz free running counter (it is used in u-boot for us timer as well). Let's use this for now. BUG=chrome-os-partner:27784 TEST=manual . with the rest of the patches applied AP148 boots all the way to trying to start the payload.
