The EDAC accesses a range of registers in the SDRAM controller.
Required properties:
-- compatible : should contain "altr,sdram-edac";
+- compatible : should contain "altr,sdram-edac" or "altr,sdram-edac-a10"
- altr,sdr-syscon : phandle of the sdr module
- interrupts : Should contain the SDRAM ECC IRQ in the
appropriate format for the IRQ controller.
