From 42ef7079224abc7c6073c0bab63f3aa6fffd5d00 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Tue, 25 Jun 2019 23:52:04 +0300 Subject: [PATCH] x86: edison: Enable SD slot Enable SD slot on Intel Edison platform. By default firmware doesn't put device on active state. Thus, we have to do this explicitly.
