From e465945672408b632d5e3c2cf7f08ade1268419e Mon Sep 17 00:00:00 2001
From: James Feist <james.feist@linux.intel.com>
Date: Thu, 24 Oct 2019 14:39:22 -0700
Subject: [PATCH 1/1] Increase default fan speed for cooper city
This increases the uboot fan speed for cooper city
as it has high core count CPUS.
Tested: In uboot fans appeared to run faster
Signed-off-by: James Feist <james.feist@linux.intel.com>
