From 8b15010b1fc6a0da76db0b5d96d12ffe69990dbe Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Sat, 20 Feb 2016 11:30:19 +0300 Subject: arc: get rid of running_on_hw ISS is obsolete now and nSIM is used for simulation instead. In its turn nSIM properly handles baud-rate settings so get rid of now useless check.
