+==============================================================================
+##### How to use this driver #####
+==============================================================================
+[..]
+This driver implements a high level communication layer for read and write from/to
+this memory. The needed STM32 hardware resources (SDMMC and GPIO) are performed by
+the user in HAL_MMC_MspInit() function (MSP layer).
+Basically, the MSP layer configuration should be the same as we provide in the
+examples.
+You can easily tailor this configuration according to hardware resources.
+[..]
+This driver is a generic layered driver for SDMMC memories which uses the HAL
+SDMMC driver functions to interface with MMC and eMMC cards devices.
+It is used as follows:
+(#)Initialize the SDMMC low level resources by implement the HAL_MMC_MspInit() API:
+(##) Enable the SDMMC interface clock using __HAL_RCC_SDMMC_CLK_ENABLE();
+(##) SDMMC pins configuration for MMC card
+(+++) Enable the clock for the SDMMC GPIOs using the functions __HAL_RCC_GPIOx_CLK_ENABLE();
+(+++) Configure these SDMMC pins as alternate function pull-up using HAL_GPIO_Init()
+and according to your pin assignment;
+(##) DMA Configuration if you need to use DMA process (HAL_MMC_ReadBlocks_DMA()
+and HAL_MMC_WriteBlocks_DMA() APIs).
+(+++) Enable the DMAx interface clock using __HAL_RCC_DMAx_CLK_ENABLE();
+(+++) Configure the DMA using the function HAL_DMA_Init() with predeclared and filled.
+(##) NVIC configuration if you need to use interrupt process when using DMA transfer.
+(+++) Configure the SDMMC and DMA interrupt priorities using functions
+HAL_NVIC_SetPriority(); DMA priority is superior to SDMMC's priority
+(+++) Enable the NVIC DMA and SDMMC IRQs using function HAL_NVIC_EnableIRQ()
+(+++) SDMMC interrupts are managed using the macros __HAL_MMC_ENABLE_IT()
+and __HAL_MMC_DISABLE_IT() inside the communication process.
+(+++) SDMMC interrupts pending bits are managed using the macros __HAL_MMC_GET_IT()
+and __HAL_MMC_CLEAR_IT()
+(##) NVIC configuration if you need to use interrupt process (HAL_MMC_ReadBlocks_IT()
+and HAL_MMC_WriteBlocks_IT() APIs).
+(+++) Configure the SDMMC interrupt priorities using function
+HAL_NVIC_SetPriority();
+(+++) Enable the NVIC SDMMC IRQs using function HAL_NVIC_EnableIRQ()
+(+++) SDMMC interrupts are managed using the macros __HAL_MMC_ENABLE_IT()
+and __HAL_MMC_DISABLE_IT() inside the communication process.
+(+++) SDMMC interrupts pending bits are managed using the macros __HAL_MMC_GET_IT()
+and __HAL_MMC_CLEAR_IT()
+(#) At this stage, you can perform MMC read/write/erase operations after MMC card initialization
+*** MMC Card Initialization and configuration ***
+================================================
+[..]
+To initialize the MMC Card, use the HAL_MMC_Init() function. It Initializes
+SDMMC IP (STM32 side) and the MMC Card, and put it into StandBy State (Ready for data transfer).
+This function provide the following operations:
+(#) Initialize the SDMMC peripheral interface with defaullt configuration.
+The initialization process is done at 400KHz. You can change or adapt
+this frequency by adjusting the "ClockDiv" field.
+The MMC Card frequency (SDMMC_CK) is computed as follows:
+SDMMC_CK = SDMMCCLK / (ClockDiv + 2)
+In initialization mode and according to the MMC Card standard,
+make sure that the SDMMC_CK frequency doesn't exceed 400KHz.
+This phase of initialization is done through SDMMC_Init() and
+SDMMC_PowerState_ON() SDMMC low level APIs.
+(#) Initialize the MMC card. The API used is HAL_MMC_InitCard().
+This phase allows the card initialization and identification
+and check the MMC Card type (Standard Capacity or High Capacity)
+The initialization flow is compatible with MMC standard.
+This API (HAL_MMC_InitCard()) could be used also to reinitialize the card in case
+of plug-off plug-in.
+(#) Configure the MMC Card Data transfer frequency. By Default, the card transfer
+frequency is set to 24MHz. You can change or adapt this frequency by adjusting
+the "ClockDiv" field.
+In transfer mode and according to the MMC Card standard, make sure that the
+SDMMC_CK frequency doesn't exceed 25MHz and 50MHz in High-speed mode switch.
+To be able to use a frequency higher than 24MHz, you should use the SDMMC
+peripheral in bypass mode. Refer to the corresponding reference manual
+for more details.
+(#) Select the corresponding MMC Card according to the address read with the step 2.
+(#) Configure the MMC Card in wide bus mode: 4-bits data.
+*** MMC Card Read operation ***
+==============================
+[..]
+(+) You can read from MMC card in polling mode by using function HAL_MMC_ReadBlocks().
+This function allows the read of 512 bytes blocks.
+You can choose either one block read operation or multiple block read operation
+by adjusting the "NumberOfBlocks" parameter.
+After this, you have to ensure that the transfer is done correctly. The check is done
+through HAL_MMC_GetCardState() function for MMC card state.
+(+) You can read from MMC card in DMA mode by using function HAL_MMC_ReadBlocks_DMA().
+This function allows the read of 512 bytes blocks.
+You can choose either one block read operation or multiple block read operation
+by adjusting the "NumberOfBlocks" parameter.
+After this, you have to ensure that the transfer is done correctly. The check is done
+through HAL_MMC_GetCardState() function for MMC card state.
+You could also check the DMA transfer process through the MMC Rx interrupt event.
+(+) You can read from MMC card in Interrupt mode by using function HAL_MMC_ReadBlocks_IT().
+This function allows the read of 512 bytes blocks.
+You can choose either one block read operation or multiple block read operation
+by adjusting the "NumberOfBlocks" parameter.
+After this, you have to ensure that the transfer is done correctly. The check is done
+through HAL_MMC_GetCardState() function for MMC card state.
+You could also check the IT transfer process through the MMC Rx interrupt event.
+*** MMC Card Write operation ***
+===============================
+[..]
+(+) You can write to MMC card in polling mode by using function HAL_MMC_WriteBlocks().
+This function allows the read of 512 bytes blocks.
+You can choose either one block read operation or multiple block read operation
+by adjusting the "NumberOfBlocks" parameter.
+After this, you have to ensure that the transfer is done correctly. The check is done
+through HAL_MMC_GetCardState() function for MMC card state.
+(+) You can write to MMC card in DMA mode by using function HAL_MMC_WriteBlocks_DMA().
+This function allows the read of 512 bytes blocks.
+You can choose either one block read operation or multiple block read operation
+by adjusting the "NumberOfBlocks" parameter.
+After this, you have to ensure that the transfer is done correctly. The check is done
+through HAL_MMC_GetCardState() function for MMC card state.
+You could also check the DMA transfer process through the MMC Tx interrupt event.
+(+) You can write to MMC card in Interrupt mode by using function HAL_MMC_WriteBlocks_IT().
+This function allows the read of 512 bytes blocks.
+You can choose either one block read operation or multiple block read operation
+by adjusting the "NumberOfBlocks" parameter.
+After this, you have to ensure that the transfer is done correctly. The check is done
+through HAL_MMC_GetCardState() function for MMC card state.
+You could also check the IT transfer process through the MMC Tx interrupt event.
+*** MMC card status ***
+======================
+[..]
+(+) The MMC Status contains status bits that are related to the MMC Memory
+Card proprietary features. To get MMC card status use the HAL_MMC_GetCardStatus().
+*** MMC card information ***
+===========================
+[..]
+(+) To get MMC card information, you can use the function HAL_MMC_GetCardInfo().
+It returns useful information about the MMC card such as block size, card type,
+block number ...
+*** MMC card CSD register ***
+============================
+[..]
+(+) The HAL_MMC_GetCardCSD() API allows to get the parameters of the CSD register.
+Some of the CSD parameters are useful for card initialization and identification.
+*** MMC card CID register ***
+============================
+[..]
+(+) The HAL_MMC_GetCardCID() API allows to get the parameters of the CID register.
+Some of the CID parameters are useful for card initialization and identification.
+*** MMC HAL driver macros list ***
