[PATCH v4 4/4] memory: Add ECC property

From: Simon Glass
Date: Tue Aug 29 2023 - 15:19:25 EST


Some memories provides ECC correction. For software which wants to check
memory, it is helpful to see which regions provide this feature.

Add this as a property of the /memory nodes, since it presumably follows
the hardware-level memory system.
