From 7c2ca877fee42085ad1b6ff24d9d10d91dcd9332 Mon Sep 17 00:00:00 2001 From: Simon Glass <sjg@chromium.org> Date: Thu, 25 Apr 2019 21:58:46 -0600 Subject: [PATCH] x86: Support booting with TPL Some boards want to use TPL as the first phase of U-Boot. This allows selection of A or B SPL phases, thus allowing the memory init to be upgraded in the field. Add a new Kconfig option for this.
