Hi Terry,
So I guess: mmc_init calls mmc_send_op_cond that set high_capacity, than it calls mmc_startup, that, with MMC_CMD_SEND_CSD command, set the capacity, using values in CSD register. So I guess that mmc_change_freq should not recalculate high_capacity.
It seems better, isn't it?
Regards, Raffaele
Finally I think that it is enough to apply the following patch in order to fix the issue.
