For some time now you have to have clocks support to be able to get SMP  
and co working. Without that and DT it doesn't really make sense to submit  
those patches.

Mostly the same as above. Don't forget that DT support will essentially  
get rid of all separate board support files, so those patches will have to  
be translated to dts files instead.

Since I'm doing all the OpenWrt work (as well as upstreaming non-ARM  
stuff) in my free time, things got stuck and will likely stay that way for  
another month or so.
