Freescale L2 Cache Controller
|
||||
|
||||
L2 cache is present in Freescale's QorIQ and QorIQ Qonverge platforms.
|
||||
The cache bindings explained below are ePAPR compliant
|
||||
|
||||
Required Properties:
|
||||
|
||||
- compatible : Should include "fsl,chip-l2-cache-controller" and "cache"
|
||||
where chip is the processor (bsc9132, npc8572 etc.)
|
||||
- reg : Address and size of L2 cache controller registers
|
||||
- cache-size : Size of the entire L2 cache
|
||||
- interrupts : Error interrupt of L2 controller
|
||||
- cache-line-size : Size of L2 cache lines
|
||||
|
||||
Example:
|
||||
|
||||
L2: l2-cache-controller@20000 {
|
||||
compatible = "fsl,bsc9132-l2-cache-controller", "cache";
|
||||
reg = <0x20000 0x1000>;
|
||||
cache-line-size = <32>; // 32 bytes
|
||||
cache-size = <0x40000>; // L2,256K
|
||||
interrupts = <16 2 1 0>;
|
||||
};

Freescale DDR memory controller
|

|

Properties:

- compatible : Should include "fsl,chip-memory-controller" where

chip is the processor (bsc9132, mpc8572 etc.), or

"fsl,qoriq-memory-controller".
|
||||
- reg : Address and size of DDR controller registers
|
||||
- interrupts : Error interrupt of DDR controller
|

|

Example 1:

|

memory-controller@2000 {
|

compatible = "fsl,bsc9132-memory-controller";
|

reg = <0x2000 0x1000>;
|
||||
interrupts = <16 2 1 8>;
|
||||
};

Example 2:
|
||||
|
||||
ddr1: memory-controller@8000 {
|
||||
compatible = "fsl,qoriq-memory-controller-v4.7",
|

|

reg = <0x8000 0x1000>;

interrupts = <16 2 1 23>;

Wherever applicable, the IP version of the USB controller should
