From 272da3279df191f028fd63d1683e5ecd56fcb13b Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Tue, 16 Jun 2020 19:14:17 +0900 Subject: tools/bootconfig: Fix to use correct quotes for value Fix bootconfig tool to select double or single quotes correctly according to the value. If a bootconfig value includes a double quote character, we must use single-quotes to quote that value.
