Have you fixed this?

For 32 MBytes of DRAM you should have
   #define XPAR_DDR_0_SIZE                 0x2000000
in your xparameters_ml403.h file.
I can't recall the whole story, but EDK 8.2 doesn't
add this #define when generating the xparameters file,
so I had to add this line by hand for EDK 8.2 generated
files. Probably earlier EDK versions did that automatically.

But your kernel (the bootwrapper to be precise) wouldn't compile
if XPAR_DDR_0_SIZE were not defined...
Do you use uboot?

Thanks,
Andrei
