I think all the issues from the recent discussion about bootloaders also make it strongly desirable to get the SoC generic stuff out of the DTS that's shipped separately to the kernel. You've got issues on reference boards where the SoC vendor may have shipped a low quality device tree in flash and users are scared to try to reflash the board due to a lack of recovery facilities (so the less we rely on being able to update data flashed into the device the better) and you've got issues on end user projects with large, potentially distributed, teams where coordinating updates between everyone can be tricky especially if those updates need to be done in lockstep (so the less data is shipped outside the kernel the better).

Remember rmk's constant complaint about bootloaders on ARM - these are programs that need to get two registers right on kernel start and don't reliably do so.
