Block Length is Not Multiple of 4. (ROPT field in HSMCI_DMA register set to 0)
Two DMA Transfer descriptors are used to perform the HSMCI block transfer.
8. Poll CBTC[x] bit in the DMAC_EBCISR Register.
9. If a new list of buffer shall be transferred repeat step 6. Check and handle HSMCI
10. Poll FIFOEMPTY field in the HSMCI_SR.

12. Wait for XFRDONE in HSMCI_SR register.
1. Use the previous step to configure the HSMCI to perform a READ_MULTIPLE_BLOCK
2. Issue a READ_MULTIPLE_BLOCK command.
3. Program the DMA Controller to use a list of descriptors.
