From 2e2a0035d4ab520615fd13dc7c89a60a44eb6bc0 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Fri, 6 Dec 2019 21:42:24 -0700 Subject: [PATCH] x86: Add an option to include a FIT Many Intel SoCs require a FIT in order to boot properly. Add an option to include this and enable it by default. This term can be confused with FIT (Flat Image Tree) in U-Boot so the CONFIG option has to include 'X86'.
