FSP with debug info

ZVere — Sun, 10 Feb 2019 04:50:16 GMT

Hello,

I got the following output after compiling coreboot with a debug FSP for baytrail:

============= PEIM FSP v1.0 (VLYVIEW0 v0.0.3.5) =============

What should I do with this information ?

Should I use it in Intel's BCT to modify some default FSP values ?

or should I use it to modify the current devicetree.cb ?

Is there a detailed documentation explains what is the meaning of each line in the messages I got ?

Thank you,

Zvika
