+Alternate Partition Names
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Partitions may also be specified like::
+
+    devnum.hwpartnum#partname
+
+or like::
+
+    devnum.hwpartnum:partnum
+
+Where
+
+  * ``devnum`` is the MMC device number. This defaults to 0.
+  * ``hwpartnum`` is the hardware partition number. This defaults to 0 (the user
+    partition on eMMC devices).
+  * ``partname`` is the partition name on GPT devices. Partitions do not have
+    names on MBR devices.
+  * ``partnum`` is the partition number, starting from 1. The partition number 0
+    is special, and specifies that the whole device is to be used as one
+    "partition."
+
+If neither ``partname`` nor ``partnum`` is specified and there is a partition
+table, then partition 1 is used. If there is no partition table, then the whole
+device is used as one "partion." Examples of alternate partition names include
+``0.1``, ``0#boot``, and ``:3``.
