1*4882a593Smuzhiyun* Freescale PQ3 and QorIQ based Cache SRAM
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunFreescale's mpc85xx and some QorIQ platforms provide an
4*4882a593Smuzhiyunoption of configuring a part of (or full) cache memory
5*4882a593Smuzhiyunas SRAM. This cache SRAM representation in the device
6*4882a593Smuzhiyuntree should be done as under:-
7*4882a593Smuzhiyun
8*4882a593SmuzhiyunRequired properties:
9*4882a593Smuzhiyun
10*4882a593Smuzhiyun- compatible : should be "fsl,p2020-cache-sram"
11*4882a593Smuzhiyun- fsl,cache-sram-ctlr-handle : points to the L2 controller
12*4882a593Smuzhiyun- reg : offset and length of the cache-sram.
13*4882a593Smuzhiyun
14*4882a593SmuzhiyunExample:
15*4882a593Smuzhiyun
16*4882a593Smuzhiyuncache-sram@fff00000 {
17*4882a593Smuzhiyun	fsl,cache-sram-ctlr-handle = <&L2>;
18*4882a593Smuzhiyun	reg = <0 0xfff00000 0 0x10000>;
19*4882a593Smuzhiyun	compatible = "fsl,p2020-cache-sram";
20*4882a593Smuzhiyun};
