1) What's the exact manufacturer and model of the SD Card?

2) At the top of aml8726_mmc.h are:

     #define AML_MMC_READ_TIMEOUT                 100000
     #define AML_MMC_WRITE_TIMEOUT                500000

  which control the timeouts.  You can try doubling them
  to see if that helps.

3) Try a different make / model SD Card.
