manual configurations to the current configurations based on the

+Making defconfig Files
+----------------------
+
+ The minimum defconfig file is simply the generated .config file with
+ CONFIG_APPS_DIR setting removed or commented out. That setting provides
+ the name and location of the apps/ directory relative to the nuttx build
+ directory. The default is ../apps/, however, the apps directory may be
+ any other location and may have a different name. For example, the name
+ of versioned NuttX releases are always in the form apps-xx.yy where xx.yy
+ is the version number.
+
+ When the default configuration is installed using on of the scripts or
+ programs in the NuttX tools directory, there will be an option to provide
+ the path to the apps/ directory. If not provided, then the configure tool
+ will look around and try to make a reasonable decision about where the
+ apps/ directory is located.
+
+ The Makefile also supports an option to generate very small defconfig
+ files. The .config files are quite large and complex. But most of the
+ settings in the .config file simply have the default settings from the
+ Kconfig files. These .config files can be converted into small defconfig
+ file:
+
+ make savedefconfig
+
+ That make target will generate a defconfig file in the top-level
+ directory. The size reduction is really quite remarkable:
+
+ $ wc -l .config defconfig
+ 1085 .config
+ 82 defconfig
+ 1167 total
+
+ In order to be usable, the .config file installed from the compressed
+ defconfig file must be reconstituted using:
+
+ make olddefconfig
+
+ CAUTION: There is only one caution. This size reduction was
+ accomplished by removing all setting from the .config file that were at
+ the default value. 'make olddefconfig' can regenerate the original
+ .config file by simply restoring those default settings. The underlying
+ assumption here is, of course, that the default settings do not change.
+ If the default settings change, and they often do, then the original
+ .config may not be reproducible.
+
+Configuring with "Compressed" defconfig Files
+---------------------------------------------
+
+ 2017-07-08: Currently all defconfig files are in .config form. However,
+ in the long term I would hope that the defconfig files will eventual
+ all be converted to the "compressed" defconfig format. This would be
+ a great savings in the total size of the NuttX files.
+
+ As described in the previous section, "Making defconfig Files," defconfig
+ files may be "compressed" using 'make savedeconfig'. These compressed
+ defconfig files may not be fully usable and may not build the target
+ binaries that you want because the compression process removed all of the
+ default settings from the defconfig file. To restore the default
+ settings, you should run the following after configuring:
+
+ make olddefconfig
+
+ That will restore the the missing defaulted values.
+
+ Using this command after configuring is generally a good practice anyway:
+ Even if the defconfig files are not "compressed" in this fashion, the
+ defconfig file may be old and the only way to assure that the installed
+ .config is is uptodate is via 'make oldconfig' or 'make olddefconfig'.
+ See the paragraph above entitled ""Refreshing Configurations" for
+ additional information.

+ * pointer to configuration data read from a file or serial FLASH,
+ * or whatever you would like to do with it. Every implementation
+ * should accept zero/NULL as a default configuration.
