Why do we need any ARM specific code at all?  What's the difference
between an ARM and - say - a PowerPC system in this respect, and why
do we need different code for both?

If we consolidate code, it should always be done in a cross-platform
way, unless platform specifc code really cannot be avoided (which I
fail to see yet here).

Best regards,

Wolfgang Denk
