2016-06-25EDAC, altera: Add Arria10 Ethernet EDAC supportThor Thayer1-0/+3
Add Altera Arria10 Ethernet FIFO memory EDAC support. Update to support a common compatibility string for all Ethernet FIFOs in the DT.

2016-06-24EDAC, altera: Add panic flag check to A10 IRQThor Thayer1-0/+1
In preparation for additional memory module ECCs, the IRQ function will check a panic flag before doing a kernel panic on double bit errors. OCRAM uncorrectable errors cause a panic because sleep/resume functions and FPGA contents during sleep are stored in OCRAM. ECCs on peripheral FIFO buffers will not cause a kernel panic on DBERRs because the packet can be retried and therefore recovered.

2016-06-08EDAC, altera: Add ECC Manager IRQ controller supportThor Thayer1-2/+3
To better support child devices, the ECC manager needs to be implemented as an IRQ controller.

2016-04-02EDAC, altera: Extract error inject operations to a struct fopsThor Thayer1-0/+1
In preparation for the Arria10 peripheral ECCs, extract the inject file operations because the Arria10 IRQ trigger mechanism is different than Cyclone5/Arria5 and Arria10 L2 cache.

2016-03-29EDAC, altera: Add Arria10 L2 Cache ECC handlingThor Thayer1-0/+42
Add a private data structure for Arria10 L2 cache ECC and the probe function for it. The Arria10 ECC device IRQs are in a shared register so the ECC Manager parent/child relationship requires a different probe function.

2016-03-29EDAC, altera: Remove platform device from check_deps()Thor Thayer1-1/+3
In preparation for the Arria10 peripheral ECCs, remove the platform device parameter from the check_deps() functions because it is not needed and makes the Arria10 check_deps() cleaner.

2015-10-15EDAC, altera: SoCFPGA EDAC should not look for ECC_CORR_ENDinh Nguyen1-2/+1
The bootloader may or may not enable the ECC_CORR_EN bit. By not enabling ECC_CORR_EN, when error happens, it is the user's responsibility to perform a full SDRAM scrub. Remove the check for ECC_CORR_EN.

2015-06-24EDAC, altera: Add Arria10 EDAC supportThor Thayer1-0/+85
The Arria10 SDRAM and ECC system differs significantly from the Cyclone5 and Arria5 SoCs. This patch adds support for the Arria10 SoC. 1) IRQ handler needs to support SHARED IRQ 2) Support sberr and dberr address reporting.

2015-06-24EDAC, altera: Refactor for Altera CycloneV SoCThor Thayer1-0/+116
The Arria10 SoC uses a completely different SDRAM controller from the earlier CycloneV and ArriaV SoCs.
