I read a document form xilinx titled "MicroBlaze Platform Flash/PROM Boot Loader and User Data Storage" that shows how to read user data from platform falsh. Is it possible to load user data to ML403's platfrom flash?
How can i mix my data with FPGA .bit file?

You can append user data to your bit file but not "mix" it. The bit file should stay intact without changes and the User Data can be put in the free space above the bit file in the flash address space. This app note will help -

First of all, thank you for your good answer. your answer covers my second qusetion. but, how about the first one? I want to know is it possible especially for "ML403" to load user data to platform flash?

Thank all of you for your answers
I read the document.one of proposed schematics for loading data from platform flash is as fllows
An I/O pin is needed to clock the platform flash and read data from it. I reviewed the ML403 schematics pdf file,
but didn't find such an IO pin.
How can I become sure about possibility of loading data from platform flash on ML403?

The User IO is only a requirement if the FPGA is in Master mode. If you set the configuration mode to slave where the PROM connnects the clock then teh CCLK can be supplied from the FPGA logis using the startup primitive -
