From 86034a959a91fbb09fb02af708764a544161df9b Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Sun, 31 Mar 2019 09:18:29 -0500 Subject: [PATCH] ARM: am3517_evm: Add spl_start_uboot for Falcon Mode When booting the am3517-evm, the following message appears: SPL: Please implement spl_start_uboot() for your board SPL: Direct Linux boot not active! This patch implements spl_start_uboot to clear this message and allow device to know if it should boot U-Boot or kernel.
