The CoreNet coherency fabric is a fabric-oriented, conectivity infrastructure that enables the implementation of coherent, multicore systems. The CCF acts as a central interconnect for cores, platform-level caches, memory subsystem, peripheral devices and I/O host bridges in the system.

DESCRIPTION
|
|
|
|
The CoreNet coherency fabric is a fabric-oriented, connectivity infrastructure
|
|
that enables the implementation of coherent, multicore systems.
|
|
|
|
Required properties:
|
|
|
|
- compatible: <string list>
|
|
fsl,corenet1-cf - CoreNet coherency fabric version 1.
|
|
Example chips: T4240, B4860
|
|
|
|
fsl,corenet2-cf - CoreNet coherency fabric version 2.
|
|
Example chips: P5040, P5020, P4080, P3041, P2041
|
|
|
|
fsl,corenet-cf - Used to represent the common registers
|
|
between CCF version 1 and CCF version 2. This compatible
|
|
is retained for compatibility reasons, as it was already
|
|
used for both CCF version 1 chips and CCF version 2
|
|
chips. It should be specified after either
|
|
"fsl,corenet1-cf" or "fsl,corenet2-cf".
|
|
|
|
- reg: <prop-encoded-array>
|
|
A standard property. Represents the CCF registers.
|
|
|
|
- interrupts: <prop-encoded-array>
|
|
Interrupt mapping for CCF error interrupt.
|
|
|
|
- fsl,ccf-num-csdids: <u32>
|
|
Specifies the number of Coherency Subdomain ID Port Mapping
|
|
Registers that are supported by the CCF.
|
|
|
|
- fsl,ccf-num-snoopids: <u32>
|
|
Specifies the number of Snoop ID Port Mapping Registers that
|
|
are supported by CCF.
|
|
|
|
Example:
|
|
|
|
corenet-cf@18000 {
|
|
compatible = "fsl,corenet2-cf", "fsl,corenet-cf";
|
|
reg = <0x18000 0x1000>;
|
|
interrupts = <16 2 1 31>;
|
|
fsl,ccf-num-csdids = <32>;
|
|
fsl,ccf-num-snoopids = <32>;
|
|
};
