+Subject: [PATCH] skip rules for mmc rpmb partition
+
+Upstream-status: Pending
+
+In FSL SDK 1.6 Kernel, mmc driver has created a new partition 
+with "mmcblkXrpmb" if device expresses it support of RPMB.
+
+RPMB (Replay Protected Memory Block), A signed access to a Replay 
+Protected Memory Block is provided. This function provides means 
+for the system to store data to the specific memory area in an 
+authenticated and replay protected manner.
+
+In that case, any read/write access to this partition device will 
+report errors which will not impact any fuction.
+
+add rules to skip it.
