From 028d1f8dc2ca9108e06f1cd05ab9d035af05ff51 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 19 Sep 2023 21:00:08 -0600 Subject: [PATCH] x86: coreboot: Enable CONFIG_SYS_NS16550_MEM32 The debug UART on modern machines uses a 32-bit wide transfer. Without this, setting debug output causes a hang or no output. It is not obvious (when enabling CONFIG_DEBUG_UART) that this is needed. Enable 32-bit access to avoid this trap.
