From 60c7f4cb1fa4df62b7ba07e9b087728ca7ce5bc8 Mon Sep 17 00:00:00 2001 From: Frank Rowand Date: Tue, 2 Feb 2016 11:02:35 -0800 Subject: [PATCH] scripts/dtc: dtx_diff - add info to error message If kernel config options are not properly set, "make scripts" will not compile dtc. Update the unable to find dtc error message to check the kernel config and give better advice on how to create dtc. Reword another error message to increase clarity.
