Alex Bennée	78e24848f6	semihosting: split console_out into string and char versions ... This is ostensibly to avoid the weirdness of len looking like it might come from a guest and sometimes being used. While we are at it fix up the error checking for the arm-linux-user implementation of the API which got flagged up by Coverity (CID 1401700).

Alex Bennée	4e7f9032cf	semihosting: enable chardev backed output for console ... 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. Signed-off-by: Alex Bennée <alex.bennee@linaro.org>	2019-05-28 10:28:50 +01:00
