+/**
+ *   @brief FFDC Package structure and definitions based on SBE chip-op spec.
+ *
+ *   SBE FFDC Starts with a header word (Word 0) that has an unique magic
+ *   identifier code of 0xFFDC followed by the length of the FFDC package
+ *   including the header itself. Word 1 contains a sequence id ,
+ *   command-class and command fields.
+ *   The sequence id field is ignored on the BMC side.
+ *   Word 2 contains a 32 bit Return Code which acts like the key to the
+ *   contents of subsequent FFDC Data Words (0-N).
+ *
+ *   A FFDC package can typically contain debug data from either:
+ *    1. A failed hardware procedure (e.g. local variable values
+ *       at point of failure) or
+ *    2. SBE firmware (e.g. traces, attributes and other information).
+ *    ___________________________________________________________
+ *   |        |  Byte 0   |  Byte 1  |  Byte 2    |    Byte 3   |
+ *   |----------------------------------------------------------|
+ *   | Word 0 | Magic Bytes : 0xFFDC | Length in words (N+4)    |
+ *   | Word 1 | [Sequence ID]        | Command-Class | Command  |
+ *   | Word 2 |           Return Code 0..31                     |
+ *   | Word 3 |           FFDC Data – Word 0                    |
+ *   |  ...                                                     |
