From 741e58e0fc8ecf5669ccb7cd9100c5bf68d89158 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 5 Feb 2015 22:06:10 -0700 Subject: Create a .cfg file containing the CONFIG options used to build At present CONFIG options are split across Kconfig and board config headers files. Also we have multiple files containing these CONFIG options. In order to see exactly what is being used for building, create a .cfg file which holds these options as reported by the C preprocessor.
