From 0c6a108ec1efd8498b281086d44604204196a9d5 Mon Sep 17 00:00:00 2001 From: Patrick Oppenlander Date: Fri, 4 May 2018 18:05:50 +0100 Subject: [PATCH] hw/char/cmsdk-apb-uart.c: Accept more input after character read The character frontend needs to be notified that the uart receive buffer is empty and ready to handle another character. Previously, the uart only worked correctly when receiving one character at a time.
