Hi Isaac,
I think you might be a little confused about how these PCDs operate. Here is the truth table: Mode PcdFspWrapperBootMode PcdFspModeSelection EDK II Native Mode FALSE N/A FSP Dispatch Mode TRUE 0 FSP API Mode TRUE 1 So, this change modifies the if statement to read: If (NOT FSP API Mode) Instead of: If (Native Mode) This results in the behavior for native mode and FSP dispatch mode being identical, which as you point out is the desired end state. The only reason we have a conditional statement here is to support FSP API mode, which is a known issue and expected.

Since UEFI native code is all about binary interoperability, there should be no difference between native mode and FSP dispatch mode. FV are FV, PPI are PPI, etc. These two PCD should mean the exact same thing and this shouldn't be necessary. We will look at moving all the board logic use out of edk2 and into MinPlatformPkg and board packages.
