943ad91798 EDAC, altera: Add register offset for ECC Enable
In preparation for the Arria10 peripheral ECCs, add a register offset
from the ECC base to index to the ECC enable register.

e17ced2cb6 EDAC, altera: Extract error inject operations to a struct fops
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.

588cb03ea2 EDAC, altera: Add Arria10 L2 Cache ECC handling
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.

328ca7ae81 EDAC, altera: Remove platform device from check_deps()
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.

941fd2e709 EDAC, altera: SoCFPGA EDAC should not look for ECC_CORR_EN
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.

73bcc942f4 EDAC, altera: Add Arria10 EDAC support
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.

143f4a5ac5 EDAC, altera: Refactor for Altera CycloneV SoC
The Arria10 SoC uses a completely different SDRAM controller from the
earlier CycloneV and ArriaV SoCs. This patch abstracts the SDRAM bits
for the CycloneV/ArriaV SoCs in preparation for the Arria10 support.
