config APPS_DIR
	string "Application directory"
	default "../apps"
	---help---
		Identifies the directory that builds the
		application to link with NuttX.  Default: ../apps This symbol must be assigned
		to the path to the application build directory *relative* to
		the NuttX top build direcory. If you had an application
		directory and the NuttX directory each in separate directory
		trees like this:
		
		build
		|-nuttx
		|  |
		|  `- Makefile
		`-application
		|
		`- Makefile
		
		Then you would set CONFIG_APPS_DIR=../application.

		The application direction must contain Makefile and this make
		file must support the following targets:
		
		libapps$(LIBEXT) (usually libapps.a). libapps.a is a static
		library ( an archive) that contains all of application object
		files.
		
		clean. Do whatever is appropriate to clean the application
		directories for a fresh build.
		
		distclean. Clean everthing -- auto-generated files, symbolic
		links etc. -- so that the directory contents are the same as
		the contents in your configuration management system.
		This is only done when you change the NuttX configuration.
		
		depend. Make or update the application build dependencies.
		
		When this application is invoked it will receive the setting TOPDIR like:
		
		$(MAKE) -C $(CONFIG_APPS_DIR) TOPDIR="$(TOPDIR)" <target>
		
		TOPDIR is the full path to the NuttX directory. It can be used, for
		example, to include makefile fragments (e.g., .config or Make.defs)
		or to set up include file paths.

config BUILD_2PASS
	bool "Two pass build"
	default n
	---help---
		Enables the two pass build options.

		Two-pass build options.  If the 2 pass build option is selected, then these
		options configure the make system build a extra link object. This link object
		is assumed to be an incremental (relative) link object, but could be a static
		library (archive) (some modification to this Makefile would be required if
		CONFIG_PASS1_TARGET generates an archive). Pass 1 1ncremental (relative) link
		objects should be put into the processor-specific source directory (where other
		link objects will be created).  If the pass1 obect is an archive, it could
		go anywhere.

if BUILD_2PASS
config PASS1_TARGET
	string "Pass one target"
	default ""
	---help---
		The name of the first pass build target.  This
		can be specific build target, a special build target (all, default, etc.)
		or may just be left undefined.

config PASS1_BUILDIR
	string "Pass one build directory"
	default "build"
	---help---
		The path, relative to the top NuttX build
		directory to directory that contains the Makefile to build the
		first pass object.  The Makefile must support the following targets:
		The special target CONFIG_PASS1_TARGET (if defined)
		and the usual depend, clean, and distclean targets.

config PASS1_OBJECT
	string "Pass one object"
	default ""
	---help---
		May be used to include an extra, pass1 object
		into the final link.  This would probably be the object generated
		from the CONFIG_PASS1_TARGET.  It may be available at link time
		in the arch/<architecture>/src directory.

config NUTTX_KERNEL
	bool "NuttX kernel build"
	default n
	---help---
		Builds NuttX as a separately compiled kernel.

config INTELHEX_BINARY
	bool "Intel HEX binary format"
	default n
	---help---
		Create the nuttx.hex in the Intel HEX binary format that is
		used with many different loaders. This option will use the GNU objcopy program
		and should not be selected if you are not using the GNU toolchain.

config MOTOROLA_SREC
	bool "Motorola S-Record binary format"
	default n
	---help---
		Create the nuttx.srec in the Motorola S-Record binary format that is
		used with many different loaders. This option will use the GNU objcopy program
		and should not be selected if you are not using the GNU toolchain.

config RAW_BINARY
	bool "Raw binary format"
	default n
	---help---
		Create the nuttx.bin in the raw binary format that is used with many
		different loaders using the GNU objcopy program.  This option
		should not be selected if you are not using the GNU toolchain.
