Hi Tom,
Could you help to assign this mmc patch reviewing to right person? It seems no one had reviewed it for almost half year.
And another my mmc patch also needs to be reviewed. I submitted in May. Please help. http://patchwork.ozlabs.org/patch/624448/
Thank you very much.
Best regards, Yangbo Lu

When the MMC framework was added in u-boot, the mmc_go_idle was added before mmc_send_op_cond_iter in function mmc_send_op_cond annotating that some cards seemed to need this. Actually, we still need to do this in function mmc_complete_op_cond for those cards. This has been verified on Micron MTFC4GACAECN eMMC chip.
If there is no go_idle(), then what happen? If you share the information more, i can check the more..
Best Regards, Jaehoon Chung
