From 8dda5b0e60b84f2679bd51ae4bcdbe527fa438d4 Mon Sep 17 00:00:00 2001 From: Diego Santa Cruz Date: Tue, 23 Dec 2014 10:50:31 +0100 Subject: mmc: extend the mmc hardware partitioning API with write reliability The eMMC partition write reliability settings are to be set while partitioning a device, as per the eMMC spec, so changes to these attributes needs to be done in the hardware partitioning API. This commit adds such support.
