From 0f3ef704bb8744f12d6c34b57ad7b0270070197a Mon Sep 17 00:00:00 2001 From: Martin Roth <martinroth@chromium.org> Date: Tue, 6 Oct 2020 18:11:12 -0600 Subject: soc/amd/picasso: Print values from PSP transfer buffer The PSP will now pass us data on the PSP boot mode and the production silicon level. Print these values out to save in the log. These definitions are in a vendorcode include directory that was previously only included in verstage. Add the include directory to all stages. BUG=b:170237834 TEST=Build & Boot - See values printed.
