From 9c5313dc095ccab69dc9a0e100cdbda62369d4fb Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Thu, 27 Oct 2016 23:47:06 +0900 Subject: [PATCH] ARM: uniphier: do not run harmful code for USB boot mode of LD11 ES3 The USB boot without the stand-by MPU is available on ES3 or later of LD11 SoC, but the code in this if-conditional block must not be run when booting from USB. Check if the boot device is USB, and skip the code in the case.
