Subject: [PATCH] spi: Add SPI flash test
It is useful to have a basic SPI flash test, which tests that the SPI chip,
the SPI bus and the driver are behaving.
This test erases part of the flash, writes data and reads it back as a
sanity check that all is well.
Use CONFIG_SF_TEST to enable it.

If included the div64 header file after common.h, it doesn’t hang anymore.
Do you have any suggestions?
+#include <div64.h>
#include <common.h>
Well I think div64.h should be after common, so it is fine to move it. I am not sure why that causes a hang though - do you have more details - e.g. what did you do when it hangs, what is console output? Also do you define CONFIG_CMD_SF_TEST?
