From 5f3249f5a1ac75afaf02506b155db63b6dea3bf9 Mon Sep 17 00:00:00 2001 From: Ahmad Fatoum Date: Thu, 9 Jun 2022 07:59:20 +0200 Subject: ARM: rpi: add debug_ll support for Raspberry Pi 4 The mini uart (Pins 8/10) is the primary UART on the Raspberry Pi 4 and can be set up in firmware by specifying enable_uart=1 in the config.txt. Add a DEBUG_LL implementation to use this for early debugging.
