Hi Rebecca,

Which PEI binary are you referring to? There is the PEI core, and a
collection of PEI modules (PEIMs) that do various platform related
things, including PCIe link training (and believe me, looking at that
code will make your eyes bleed), which is the only closed source PEIM
IIRC.

Whether you can get access to the FDK is a question I cannot answer,
but I don't think there are any people left at AMD working on the
Seattle project.

Which tree are you building from?
