From bcc51c1512a3deb6a9fdd37362c6dde32ad3da23 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada <yamada.masahiro@socionext.com> Date: Wed, 10 Aug 2016 16:08:41 +0900 Subject: [PATCH] ARM: uniphier: move lowlevel debug init code after page table switch As the sLD3 Boot ROM has a complex page table, it is difficult to set up the debug UART with enabling it. It will be much easier to initialize the UART port after switching over to the straight-mapped page table.
