[PATCH v2 2/2] arm64: dts: ti: k3-am64-main: Add ELM (Error Location Module) node
From: Roger Quadros <rogerq@kernel.org>

The ELM module is used for GPMC NAND accesses for detecting and correcting errors during reads due to NAND bitflips errors. 4-, 8-, and 16-bit error-correction levels are supported using the BCH (Bose-ChaudhurI-Hocquenghem) algorithm.
