+		Select the board sub-directory name where the board logic resides under
+		the configs/ directory.  Normally, the default is the correct location
+		and you probably not want to change that.  However, if you have selected
+		ARCH_BOARD_CUSTOM, then you will need to tell the build system when
+		the board logic resides.
