// Version:| Author: | Date: | Comment:
//---------|----------|---------|-----------------------------------------------
// 1.8 | bellows |14-OCT-13| One more sprintf update to make this hostboot/cronus agnostic
// 1.7 | bellows |08-OCT-13| Made update so it compiles with cronus + hostboot
// 1.6 | thi |05-OCT-13| Fix compiler error
// 1.5 | bellows |02-OCT-13| Minor Review Comments addressed
// 1.4 | bellows |27-SEP-13| Removed std::string
// 1.3 | bellows |26-SEP-13| Firware comments and error checking added
// 1.2 | bellows |25-SEP-13| Changed the format so that the ECID bits are
// | | | broken into two lines.
