I finally found a package on the CVS repository 
(packages/hal/arm/arm9/aaed2000/) which is similar to mine, at least as 
for the MMU setup. As I understood from other threads the file which 
has to be modified is /include/hal_platform_setup.h but in this case 
the code calls a function (hal_mmu_init) to create MMU tables. I've 
found the code for this function in /src/aaed2000_misc.c and actually 
it defines a MMU table using the macro X_ARM_MMU_SECTION. The first 
thing that comes into my head is to modify directly the source file 
adding the mapping for my device but maybe there's a more elegant way 
to do it. I hope to have provided all the information you need to help 
me, I'm at the beginning with eCos. Thanks a lot.
