It is strange that your card would still get failed to send CMD8 after 3 times retry. Does omap mmc controller has some mechanism of mmc dynamic clock gating? I would suggest you to investigate why the emmc cannot response to CMD8 first. If not, I think we could make this err return code included in a ifdef to workaround your issue.
