From 05244b78be9eba0c83f6267fdbb3aa34e60eec98 Mon Sep 17 00:00:00 2001 From: Yulia Garbovich Date: Tue, 23 Nov 2021 20:10:26 +0200 Subject: Move drivers to core_platform Move to core_platform repository. core_software repository should only contain components related to running an inference. Drivers are platform components.
