From 66a83c97c4545ce4f07e0d90998f906fae49caf2 Mon Sep 17 00:00:00 2001

Subject: [PATCH] fix-glamo-mci-set-default-drive-level-0.patch
Tests on access to SD Card with Glamo drive level "0" show
that it reduces SD_CLK energy at 1.5GHz by 24dBm compared to
drive level 3. This puts it only 6dB above the background
noise floor compared to 30dB and should make a solution for
GPS trouble with SD Card in.
SD card communication seems unaffected so far on the Sandisk
512MB card we ship.
