From 4e7f9032cf9bba8558b0fd5ab6a1366d6d7b8ee0 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Alex=20Benn=C3=A9e?= Date: Tue, 14 May 2019 15:30:14 +0100 Subject: semihosting: enable chardev backed output for console MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It will be useful for a number of use-cases to be able to re-direct output to a file like we do with serial output. This does the wiring to allow us to treat then semihosting console like just another character output device.
