sorry, but I'm not sure if I understand this correctly.

What I need is some minor non-intrusive changes to 83xx-specific file 
spd_sdram.c because it is the most straightforward solution with *no* 
impact on code size or other existing boards. So: The feature I ask for 
is *not* already there.

What I definitely won't do is use the "new" fsl ddr code in mpc8xxx/ddr 
because it completely lacks 83xx support.
So: The feature I ask for is there but my CPU family is not supported.
IMHO the "new" code is total overkill for 83xx.
