From 40b7455f9337605b0f3062a6feacb82f43099186 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Tue, 10 Dec 2013 09:01:41 -0800 Subject: rambi: limit SD card controller to 2.0 spec MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The rambi board can only meet the SD card 2.0 specification. Therefore, the controller capabilities need to be overridden to match. BUG=chrome-os-partner:24423 BRANCH=None TEST=Built and booted. /sys/kernel/debug/mmc0/ios shows high speed as maximum timing as well as 3.3V signal voltage.
