The majority of ARM systems are embedded designs which never use any kind of DIMM, but raw soldered-on RAM chips. > Does it make sense to share the Freescale DDR driver across ARM and > Powerpc?

If the similarity You are probably in a beter position to answer that than us - how many ARM systems are there around that use the same memory controller as the MPC8xxx? > For those who is not familiar with, Freescale is extending products to > ARM cores.

Well, I'm not sure which exact products you might have in mind here, but from what we've seen so far with the i.MX2x (and mxs), i.MX3x, iMX5x and i.MX6 systems, there are commnon IP blocks like the FEC, but so far I haven't seen this with the memory controller. And I haven't seen any single FSL ARM board in our lab yet that was using any kind ot DIMM or such.
