From a2be776dcc7556fcb67e92ba6736bade9f2d9a4a Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Thu, 23 May 2013 15:13:47 +0200 Subject: [PATCH] ARM: ux500: Enable support for RPMB and Reliable Write for eMMC By adding MMC_CAP_CMD23 for the eMMC devices, we can support RPMB and Reliable Write. Additionally it will mean CMD12 will not be sent to end a successful data transfer.
