Following Fabio's suggestion I have prepared the following patch that fixes the QSPI read support issue of the fsl_qspi driver on my i.MX7D Sabre eval system. Could you please review/check this patch and introduce it into upcoming v2019.07 version?
Thanks, Thomas

Use readl_poll_timeout function to check for busy controller with a timeout of 1000 us instead of 5 fixed test loops.

I think the change looks good, but I suggest to improve the commit log by stating that with the current code you observe timeout during QSPI read.
Please submit it as formal patch.
Thanks
