From cfe67cef48696e8b901aff38a82056ae64d69c98 Mon Sep 17 00:00:00 2001 From: Leon Alrae Date: Fri, 19 Jun 2015 14:17:45 +0100 Subject: semihosting: create SemihostingConfig structure and semihost.h Remove semihosting_enabled and semihosting_target and replace them with SemihostingConfig structure containing equivalent fields. The structure is defined in vl.c where it is actually set. Also introduce separate header file include/exec/semihost.h allowing to access semihosting config related stuff from target specific semihosting code.
