From 91a043896dfb8544db00496bee08bcf59e449dc9 Mon Sep 17 00:00:00 2001 From: Chen Baozi Date: Wed, 21 Jul 2021 14:11:26 +0800 Subject: [PATCH] serial: pl011: Enable DEBUG_UART_PL011 in SPL Commit b81406db51a6 ("arm: serial: Add debug UART capability to the pl01x driver") add supports to use pl01x as a debug UART. However, due to CONFIG_IS_ENABLED macro requires CONFIG_SPL_* prefix, the _debug_uart_init() would not choose TYPE_PL011 in SPL build. This patch fixes the bug by judging CONFIG_DEBUG_UART_PL011 explicitly.
