[Shengzhou]  T1040 RM says:
Hardware coherent PAMU Look-aside caches to improve performance
* A 32-entry, direct-mapped primary PAACT cache
* A 128-entry, 2-way, set-associative secondary PAACT cache
It appears it should be: 
       fsl,primary-cache-geometry = <32 1>;
       fsl,secondary-cache-geometry = <128 2>;

is there any reason that it was "<128 1>,  <16 2>" ?
