Hi wolfram: No, I don't prefer to skip this patch, and want to carry this patch, since these patch are used for imx53, and imx53 only support the SDHC V2. What I just want to say is that the common sd/mmc subsystem would keep coherent with spec about the multi-block IO mode after the ACMD23 is implemented in the previous email.
