Altera SoCFPGA ECC Manager
|
|
This driver uses the EDAC framework to implement the SOCFPGA ECC Manager.
|
|
The ECC Manager counts and corrects single bit errors and counts/handles
|
|
double bit errors which are uncorrectable.
|
|
|
|
Cyclone5 and Arria5 ECC Manager
|
|
Required Properties:
|
|
- compatible : Should be "altr,socfpga-ecc-manager"
|
|
- #address-cells: must be 1
|
|
- #size-cells: must be 1
|
|
- ranges : standard definition, should translate from local addresses
|
|
|
|
Subcomponents:
|
|
|
|
L2 Cache ECC
|
|
Required Properties:
|
|
- compatible : Should be "altr,socfpga-l2-ecc"
|
|
- reg : Address and size for ECC error interrupt clear registers.
|
|
- interrupts : Should be single bit error interrupt, then double bit error
|
|
interrupt. Note the rising edge type.
|
|
|
|
On Chip RAM ECC
|
|
Required Properties:
|
|
- compatible : Should be "altr,socfpga-ocram-ecc"
|
|
- reg : Address and size for ECC error interrupt clear registers.
|
|
- iram : phandle to On-Chip RAM definition.
|
|

|
|
interrupt. Note the rising edge type.
|
|
|
|
Example:
|
|
|
|
eccmgr: eccmgr@ffd08140 {
|
|
compatible = "altr,socfpga-ecc-manager";
|
|
#address-cells = <1>;
|
|
#size-cells = <1>;
|
|
ranges;

Arria10 SoCFPGA ECC Manager
|
|
The Arria10 SoC ECC Manager handles the IRQs for each peripheral
|
|
in a shared register instead of individual IRQs like the Cyclone5
|
|
and Arria5. Therefore the device tree is different as well.
|
|
|
|
Required Properties:
|
|
- compatible : Should be "altr,socfpga-a10-ecc-manager"
|
|
- altr,sysgr-syscon : phandle to Arria10 System Manager Block
|
|
containing the ECC manager registers.
|
|
- #address-cells: must be 1
|
|
- #size-cells: must be 1
|
|
- interrupts : Should be single bit error interrupt, then double bit error
|
|
interrupt.
|
|
- interrupt-controller : boolean indicator that ECC Manager is an interrupt controller
|
|
- #interrupt-cells : must be set to 2.
|
|
- ranges : standard definition, should translate from local addresses
|

Stratix10 SoCFPGA ECC Manager (ARM64)
|
|
The Stratix10 SoC ECC Manager handles the IRQs for each peripheral
|
|
in a shared register similar to the Arria10. However, Stratix10 ECC
|
|
requires access to registers that can only be read from Secure Monitor
|
|
with SMC calls. Therefore the device tree is slightly different. Note
|
|
that only 1 interrupt is sent in Stratix10 because the double bit errors
|
|
are treated as SErrors in ARM64 instead of IRQs in ARM32.
|
|
|
|
Required Properties:
|
|
- compatible : Should be "altr,socfpga-s10-ecc-manager"
|
|
- altr,sysgr-syscon : phandle to Stratix10 System Manager Block
|
|
containing the ECC manager registers.
|
|
- interrupts : Should be single bit error interrupt.

|
|
