In IMX6 solo hardware file system mounting consumes lot of time from eMMC device. Logs are

I noticed that the device is detected as high speed device. Is there any way to reduce the file system mounting time from eMMC device.

according to the log, your filesystem maybe corrupted so need to spend longer time to recover and mount it.
