+/**
+ * There are four request types that are applicable for rpmb accesses- two
+ * under read category and two under write. They are
+ *
+ *  Reads
+ *  -------
+ *  1. Read Write Counter
+ *  2. Authenticated data read
+ *
+ *
+ *  Writes
+ *  -------
+ *  1. Provision RPMB key (though it might be done in a secure environment)
+ *  2. Authenticated data write
+ *
+ *  While its given that the rpmb data frames are going to have that
+ *  information encoded in it and the frames should be generated by a secure
+ *  piece of code, the request types can be classified as above.
+ *
+ *  So here are the set of commands that should be executed atomically in the
+ *  ioctl for rpmb read operation
+ *  1. Switch partition
+ *  2. Set block count
+ *  3. Write data frame - CMD25 to write the rpmb data frame
+ *  4. Set block count
+ *  5. Read the data - CMD18 to do the actual read
+ *
+ *  Similarly for rpmb write operation, these are the commands that should be
+ *  executed atomically in the ioctl for rpmb write operation
+ *  1. Switch partition
+ *  2. Set block count
+ *  3. Write data frame - CMD25 to write the rpmb data frame with data
+ *  4. Set block count
+ *  5. Read the data - CMD25 to write rpmb data frame indicating that rpmb
+ *     result register is about to be read
+ *  6. Set block count
+ *  7. Read rpmb result - CMD18 to read the rpmb result register
+ *
+ * Each of the above commands should be sent individually via struct mmc_ioc_cmd
+ * and fields like is_acmd that are not needed for rpmb operations will be
+ * ignored.
