May I ask some questions?

[John Bonesio]

xparameters.h will #include the other xparameters_mlxxx.h file. When
using XPS in the EDK, you can use the 'software platforms settings'
dialog box to specify the peripherals to use, the size of memory to use,
and other parameters.  When this is done, you can select 'generate
libraries and bsps' which will generate an xparameters_mlxxx.h file,
where xxx is a board number. e.g. xparameters_ml40x.h, or
xparameters_ml507.h

The generated xparameters_mlxxx.h file will include the XPAR_xxx values
you need.
