Liming, Thanks for catching this case. I will send a V2 patch

Wiki is good enough. For second one, I understand its complexity. Append is optional option. Users will decide to use it or not. I don't expect to add every file for every PCD. From: Kinney, Michael D Sent: Friday, November 11, 2016 12:11 AM To: Gao, Liming ; edk2-devel@lists.01.org<mailto:edk2-devel@lists.01.org>; Kinney, Michael D Subject: RE: [edk2] [Patch] BaseTools/Scripts: Add BinToPcd utility Liming, This utility would not used as part of a build. I put it in BaseTools/Scripts because it is intended to be a helper tool for developers. I have been writing the Wiki on the Capsule Based System Firmware Update and there are development steps in that Wiki that will be simpler if this utility was available, so I plan on demonstrating real use of this utility in that Wiki. Will that address your feedback? The append concept is very complex because this utility can generate PCD statements for all the supported DSC PCD section types. So we can not append 2 PCDs with different types. I prefer to do one PCD at a time and developer can choose to combine or not into one file.
