From f7f0ad5e568862f7dc70fbd0f790845ee576734d Mon Sep 17 00:00:00 2001
From: Rabeeh Khoury <rabeeh@solid-run.com>
Date: Tue, 24 Mar 2020 03:42:14 +0200
Subject: [PATCH 8/8] lx2160a: add generic bootloc section
The generic bootloc section does conditional blockcopy from SD/eMMC and
SPI with some predefined addresses.
Later on if ATF is used; those addresses are modified with ATF's
create_pbl.c
With this method a single boot image is unified for all the 3 different
boot methods.
Upstream-Status: Inappropriate [Solid-Run BSP]
