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.

The patch series has two patches:
1. Add driver support into edac subsystem
2. Add devicetree binding in yaml format
