From 843ed983a07ee5d8d4e4ac5baa39fc53f12b5f33 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Wed, 5 Oct 2022 23:19:54 +0100 Subject: [PATCH] suniv: add UART1 support Some boards with the Allwinner F1C100s family SoCs use UART1 for its debug UART, so define the pins for the SPL and the pinmux name and mux value for U-Boot proper.
