It's a valid test case, thanks for reporting it. I missed this condition check in my patch. Let me update it. As per dw_mmc IP data book, the register offsets are different for both 32-bit and 64-bit configurations. We can't use the driver in 32-bit address mode IDMAC if the driver was compiled with the CONFIG_MMC_DW_IDMAC_64BIT_ADDRESS since it will have the register offset corresponds to 64-bit configuration. So, If there is any mismatch between software and hardware configurations, then we should not use the internal DMA. I will add this condition check and send it. > And I think that some code should reuse the existing code.. Let me try to reuse the existing code as much as possible and create a new patch.
