The part in your schematics(MT47H32M16BN) isn't available anymore on Micron's site -
Would you reconmend a part best similiar ? what should i do in order to implement a new part? change the registers settings in the ddr2 controller of the dsp?

The MT47H32M16BN device is indeed obsolete.
I was able to get this answer to your question:
You simply replace the BN with an HR, and choose whichever speed-grade is the easiest/cheapest to get.
We won't run things faster than 133 MHz on any of these boards, so any speed grade will work.
The timing parameters in the controllers of the existing designs should work without modification.
New valid devices:
