From a5f52c3f725f7472d03a116d6ea33c5b5f8619a4 Mon Sep 17 00:00:00 2001 From: Olaf Hering Date: Thu, 6 Sep 2018 16:02:58 +0200 Subject: [PATCH] xen: add DEBUG_INFO Kconfig symbol Creating debug info during build is not strictly required at runtime. Make it optional by introducing a new Kconfig knob "DEBUG_INFO". This slightly reduces build time and diskusage, if disabled.
