+ * select_hwpart() - select a particular hardware partition
+ *
+ * Some devices (e.g. MMC) can support partitioning at the hardware
+ * level. This is quite separate from the normal idea of
+ * software-based partitions. MMC hardware partitions must be
+ * explicitly selected. Once selected only the region of the device
+ * covered by that partition is accessible.
+ *
+ * The MMC standard provides for two boot partitions (numbered 1 and 2),
+ * rpmb (3), and up to 4 addition general-purpose partitions (4-7).
+ *
+ * @desc: Block device to update
+ * @hwpart: Hardware partition number to select. 0 means the raw
+ * device, 1 is the first partition, 2 is the second, etc.
+ * @return 0 if OK, -ve on error
