Subject: [PATCH 32/39] i2400m/SDIO: header for the SDIO subdriver
This contains the common function declaration and constants for the
SDIO driver for the 2400m Wireless WiMAX Connection and the debug
level settings for the SDIO driver.

+ * - Initial implementation
+ *
+ *
+ * This driver implements the bus-specific part of the i2400m for
+ * SDIO. Check i2400m.h for a generic driver description.
+ *
+ * ARCHITECTURE
+ *
+ * This driver sits under the bus-generic i2400m driver, providing the
+ * connection to the device.
+ *
+ * When probed, all the function pointers are setup and then the
+ * bus-generic code called. The generic driver will then use the
+ * provided pointers for uploading firmware (i2400ms_bus_bm*() in
+ * sdio-fw.c) and then setting up the device (i2400ms_dev_*() in
+ * sdio.c).
+ *
+ * Once firmware is uploaded, TX functions (sdio-tx.c) are called when
+ * data is ready for transmission in the TX fifo; then the SDIO IRQ is
+ * fired and data is available (sdio-rx.c), it is sent to the generic
+ * driver for processing with i2400m_rx.
