+  * @brief   This file provides a set of functions needed to manage the SDIO SD 
+  *          Card memory mounted on STM3210E-EVAL evaluation board. 
+  *          
+  *

+  *
+  *          ===================================================================
+  *                                   How to use this driver
+  *          ===================================================================
+  *          It implements a high level communication layer for read and write 
+  *          from/to this memory. The needed STM32 hardware resources (SDIO and 
+  *          GPIO) are defined in stm3210e_eval.h file, and the initialization is 
+  *          performed in SD_LowLevel_Init() function declared in stm3210e_eval.c 
+  *          file.
+  *          You can easily tailor this driver to any other development board, 
+  *          by just adapting the defines for hardware resources and 
+  *          SD_LowLevel_Init() function.
+  *
+  *          A - SD Card Initialization and configuration
+  *          ============================================    
+  *            - To initialize the SD Card, use the SD_Init() function.  It 
+  *              Initializes the SD Card and put it into StandBy State (Ready 
+  *              for data transfer). This function provide the following operations:
+  *
+  *              1 - Apply the SD Card initialization process at 400KHz and check
+  *                  the SD Card type (Standard Capacity or High Capacity). You 
+  *                  can change or adapt this frequency by adjusting the 
+  *                  "SDIO_INIT_CLK_DIV" define inside the stm3210e_eval.h file. 
+  *                  The SD Card frequency (SDIO_CK) is computed as follows:
+  *
+  *                     +---------------------------------------------+
+  *                     | SDIO_CK = SDIOCLK / (SDIO_INIT_CLK_DIV + 2) |
+  *                     +---------------------------------------------+
+  *
+  *                  In initialization mode and according to the SD Card standard, 
+  *                  make sure that the SDIO_CK frequency don't exceed 400KHz.
+  *
+  *              2 - Get the SD CID and CSD data. All these information are
+  *                  managed by the SDCardInfo structure. This structure provide
+  *                  also ready computed SD Card capacity and Block size.   
+  *
+  *              3 - Configure the SD Card Data transfer frequency. By Default,
+  *                  the card transfer frequency is set to 24MHz. You can change
+  *                  or adapt this frequency by adjusting the "SDIO_TRANSFER_CLK_DIV" 
+  *                  define inside the stm3210e_eval.h file.
+  *                  The SD Card frequency (SDIO_CK) is computed as follows:
+  *
+  *                     +---------------------------------------------+
+  *                     | SDIO_CK = SDIOCLK / (SDIO_INIT_CLK_DIV + 2) |
+  *                     +---------------------------------------------+
+  *
+  *                  In transfer mode and according to the SD Card standard, 
+  *                  make sure that the SDIO_CK frequency don't exceed 25MHz
+  *                  and 50MHz in High-speed mode switch.
+  *                  To be able to use a frequency higher than 24MHz, you should
+  *                  use the SDIO peripheral in bypass mode. Refer to the 
+  *                  corresponding reference manual for more details.
+  *
+  *              4 -  Select the corresponding SD Card according to the address
+  *                   read with the step 2.
+  *
+  *              5 -  Configure the SD Card in wide bus mode: 4-bits data.
+  *
+  *          B - SD Card Read operation
+  *          ========================== 
+  *           - You can read SD card by using two function: SD_ReadBlock() and
+  *             SD_ReadMultiBlocks() functions. These functions support only
+  *             512-byte block length.
+  *           - The SD_ReadBlock() function read only one block (512-byte). This
+  *             function can transfer the data using DMA controller or using 
+  *             polling mode. To select between DMA or polling mode refer to 
+  *             "SD_DMA_MODE" or "SD_POLLING_MODE" inside the stm3210e_eval_sdio_sd.h
+  *             file and uncomment the corresponding line. By default the SD DMA
+  *             mode is selected          
+  *           - The SD_ReadMultiBlocks() function read only mutli blocks (multiple 
+  *             of 512-byte). 
+  *           - Any read operation should be followed by two functions to check
+  *             if the DMA Controller and SD Card status.
+  *              - SD_ReadWaitOperation(): this function insure that the DMA
+  *                controller has finished all data transfer.
+  *              - SD_GetStatus(): to check that the SD Card has finished the 
+  *                data transfer and it is ready for data.
+  *
+  *           - The DMA transfer is finished by the SDIO Data End interrupt. 
+  *             User has to call the SD_ProcessIRQ() function inside the SDIO_IRQHandler()
+  *             and SD_ProcessDMAIRQ() function inside the DMA2_Channel4_5_IRQHandler().
+  *             Don't forget to enable the SDIO_IRQn and DMA2_Channel4_5_IRQn 
+  *             interrupts using the NVIC controller.
+  *
+  *          C - SD Card Write operation
+  *          =========================== 
+  *           - You can write SD card by using two function: SD_WriteBlock() and
+  *             SD_WriteMultiBlocks() functions. These functions support only
+  *             512-byte block length.   
+  *           - The SD_WriteBlock() function write only one block (512-byte). This
+  *             function can transfer the data using DMA controller or using 
+  *             polling mode. To select between DMA or polling mode refer to 
+  *             "SD_DMA_MODE" or "SD_POLLING_MODE" inside the stm3210e_eval_sdio_sd.h
+  *             file and uncomment the corresponding line. By default the SD DMA
+  *             mode is selected          
+  *           - The SD_WriteMultiBlocks() function write only mutli blocks (multiple 
+  *             of 512-byte). 
+  *           - Any write operation should be followed by two functions to check
+  *             if the DMA Controller and SD Card status.
+  *              - SD_ReadWaitOperation(): this function insure that the DMA
+  *                controller has finished all data transfer.
+  *              - SD_GetStatus(): to check that the SD Card has finished the 
+  *                data transfer and it is ready for data.
+  *
+  *           - The DMA transfer is finished by the SDIO Data End interrupt. 
+  *             User has to call the SD_ProcessIRQ() function inside the SDIO_IRQHandler()
+  *             and SD_ProcessDMAIRQ() function inside the DMA2_Channel4_5_IRQHandler().
+  *             Don't forget to enable the SDIO_IRQn and DMA2_Channel4_5_IRQn 
+  *             interrupts using the NVIC controller.
+  *
+  *
+  *          D - SD card status
+  *          ================== 
+  *           - At any time, you can check the SD Card status and get the SD card
+  *             state by using the SD_GetStatus() function. This function checks
+  *             first if the SD card is still connected and then get the internal
+  *             SD Card transfer state.     
+  *           - You can also get the SD card SD Status register by using the 
+  *             SD_SendSDStatus() function.
+  *
+  *          E - Programming Model (Selecting DMA for SDIO data Transfer)
+  *          ============================================================
