How much? More than 0x98000000? The RTD1395 datasheet says up to 4 GB - does that mean it continues in a second region beyond 0xffffffff? Those locations should be excluded in the soc node ranges (which you sadly appear to have dropped in v2).
I'll try to post a patch for RTD1295 soon to demonstrate, it's just a little time-consuming with the 100+ commits on top of linux-next that need to be rebased then... RTD1195 may be quicker.
