Subject: [PATCH v1 0/2] Add EDAC support for Cadence ddr controller

These patches add new edac driver for Cadence ddr memory controller.
Cadence controller detects single(CE) and double(UE) bit errors during
memory operations(RMW). DDR controller raised the interrupt on detection
of the ecc error event and fill the data into registers. Driver handle
the interrupt event and notify edac subsystem about ecc errors.

Changes since v1:
=================
- Made predefined arrays as static
 Fixes: 201447a5db9b ("EDAC/Cadence:Add EDAC driver for cadence memory controller")
- Replace macro 'EDAC_DIMM_PTR' with newly introduce function
- Removed unused variable root
