From 2af9faba171a0480e77d916fca825c2434999658 Mon Sep 17 00:00:00 2001 From: Chris Packham Date: Fri, 17 Aug 2018 20:47:41 +1200 Subject: [PATCH] Revert "arm: mvebu: fix boot from UART when in fallback mode" This reverts commit 2da04caa3421014651df7e2e29235cbe40a2cef1. This prevents kwboot from overriding the hardware strapped boot source.
