     1 Aspeed BMC SoC EDAC node
    2 
    3 The Aspeed BMC SoC supports DDR3 and DDR4 memory with and without ECC (error
    4 correction check).
    5 
    6 The memory controller supports SECDED (single bit error correction, double bit
    7 error detection) and single bit error auto scrubbing by reserving 8 bits for
    8 every 64 bit word (effectively reducing available memory to 8/9).
    9 
   10 Note, the bootloader must configure ECC mode in the memory controller.
   11 
   12 
   13 Required properties:
   14 - compatible: should be one of
   15         - "aspeed,ast2400-sdram-edac"
   16         - "aspeed,ast2500-sdram-edac"
   17         - "aspeed,ast2600-sdram-edac"
   18 - reg:        sdram controller register set should be <0x1e6e0000 0x174>
   19 - interrupts: should be AVIC interrupt #0

   22 Example:
   23 
   24         edac: sdram@1e6e0000 {
   25                 compatible = "aspeed,ast2500-sdram-edac";
   26                 reg = <0x1e6e0000 0x174>;
   27                 interrupts = <0>;
   28         };
