Re: [RFC v2 0/4] Add FmpDevicePkg

["Kinney, Michael D" <michael.d.kinney@intel.com>]

Star,

Thanks for the feedback.  I think the "BuildTime" helps
clarify the scope and usage of this PCD.  The 
LowestSupportedVersion name is used in many places.  
The name of this PCD clarifies that this is the 
LowestSupportedVersion value provided at the time the 
FmpDxe module was built and is only used when the 
LowestSupportedVersion value is not available from 
any other source.

Mike
