From 022885cb9ce9b22fb62225a21b4eb017a2e8dab5 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 30 Jun 2016 10:52:20 -0600 Subject: [PATCH] tools: Allow building with debug enabled Sometimes it is useful to build tools with debugging information included so that line-number information is available when run under gdb. Add a Kconfig option to support this.
