Does iop13xx support cache coherent?

[s ticket]

Hello, everyone
     I am now doing some work on IOP13xx platform.
     It seems that there is a 'arch_is_coherent()' macro in arm
architecture, but only ixp23xx support it ?

     Does iop13xx support coherent and does arm-linux support it?

    Thx for advance.
