title: Aspeed BMC SoC SDRAM EDAC controller

maintainers:
  - Stefan Schaeckeler <sschaeck@cisco.com>

description: >
  The Aspeed BMC SoC supports DDR3 and DDR4 memory with and without ECC (error
  correction check).

  The memory controller supports SECDED (single bit error correction, double bit
  error detection) and single bit error auto scrubbing by reserving 8 bits for
  every 64 bit word (effectively reducing available memory to 8/9).

  Note, the bootloader must configure ECC mode in the memory controller.
