I have `zynq-microzed` board.

Here is my log messages of `U-BOOT`.

See CONFIG_BOOTSTAGE which will measure the time and CONFIG_BOOTSTAGE_REPORT which will print a report when the kernel boots.

You probably only need either crc32 or sha1 - not a lot of point in both.

It takes `0.344ms.` But i want to reduce this time more. I am using `image.ub` for kernel image.

Can you please tell me what should i do?

Be happy. That's very fast :-)
