description: |
The Nuvoton BMC SoC supports DDR4 memory with or without ECC (error correction
check).
The memory controller supports single bit error correction, double bit error
detection (in-line ECC in which a section (1/8th) of the memory device used to
store data is used for ECC storage).
Note, the bootloader must configure ECC mode for the memory controller.
