The only requirement the current mcelog parser has is
(that is what it actually uses, it parses more things but I abandoned
them):

- List of DIMMs (type 17) 
- It's useful if they have the correct size for display to the user.
- Correct serial/part numbers/manufacturer are also useful (for display), but
not strictly required.
- Locator should match the silk screen label of the DIMM on the board
- Bank Locator is in the format prefix_Node%u_Channel%u_Dimm%u
prefix can be arbitary, but should not contain '_'
Node matching SOCKETID coming from CPU, Channel matching Channel, Dimm
matching Dimm number from CPU.
This requirement is the only extension over the standard.
