From 1feac813fe54ff6466ea2d575960bc1de45b0e5c Mon Sep 17 00:00:00 2001 From: Teresa Remmet Date: Wed, 7 Jul 2021 12:57:59 +0000 Subject: [PATCH] board: phytec: phycore_imx8mp: Change debug UART With the first redesign the debug UART had changed from UART2 to UART1. As the first hardware revision is considered as alpha and will not be supported in future. The old setup will not be preserved.
