Thanks a lot Sean, I’ll try out the TXE when I have something booting.

It looks like it goes through every FSP phase now except the ReadyToBoot phase. 
I’ve added the log ( debug log level ), configuration and rom layout as attachments. 

I’ve gone through the log myself, but can’t really find anything out of the ordinary.
The 4digit hex display shows the code 0110, after which the board shuts down. 
This is probably set by the FSP during the FspNotify call. There doesn’t really seem to be any documentation on the error codes used by the FSP, which is a shame.
Hopefully someone knows what I might have missed here.
Getting really close now!
