/*
* FIXME: the type of error detection actually depends of the
* mode of operation. When it is just one single memory chip, at
* socket 0, channel 0, it uses 8-byte-over-32-byte SECDED+ code.
* In normal or mirrored mode, it uses Single Device Data correction,
* with the possibility of using an extended algorithm for x8 memories
* See datasheet Sections 7.3.6 to 7.3.8
