+	Usage: MAKEALL [options] [--] [boards-to-build]
+
+	Options:
+	  -a ARCH,   --arch ARCH       Build all boards with arch ARCH
+	  -c CPU,    --cpu CPU         Build all boards with cpu CPU
+	  -v VENDOR, --vendor VENDOR   Build all boards with vendor VENDOR
+	  -s SOC,    --soc SOC         Build all boards with soc SOC
+	  -b BOARD,  --board BOARD     Build all boards with board name BOARD
+	  -l,        --list            List all targets to be built
+	  -m,        --maintainers     List all targets and maintainer email
+	  -M,        --mails           List all targets and all affilated emails
+	  -C,        --check           Enable build checking
+	  -n,        --continue        Continue (skip boards already built)
+	  -r,        --rebuild-errors  Rebuild any boards that errored
+	  -h,        --help            This help output
+
+	Selections by these options are logically ANDed; if the same option
+	is used repeatedly, such selections are ORed.  So "-v FOO -v BAR"
+	will select all configurations where the vendor is either FOO or
+	BAR.  Any additional arguments specified on the command line are
+	always build additionally.  See the boards.cfg file for more info.
+
+	If no boards are specified, then the default is "powerpc".
+
+	Environment variables:
+	  BUILD_NCPUS      number of parallel make jobs (default: auto)
+	  CROSS_COMPILE    cross-compiler toolchain prefix (default: "")
+	  CROSS_COMPILE_<ARCH> cross-compiler toolchain prefix for
+			   architecture "ARCH".  Substitute "ARCH" for any
+			   supported architecture (default: "")
+	  MAKEALL_LOGDIR   output all logs to here (default: ./LOG/)
+	  BUILD_DIR        output build directory (default: ./)
+	  BUILD_NBUILDS	   number of parallel targets (default: 1)
+
+	Examples:
+	  - build all Power Architecture boards:
+	      MAKEALL -a powerpc
+	      MAKEALL --arch powerpc
+	      MAKEALL powerpc
+	  - build all PowerPC boards manufactured by vendor "esd":
+	      MAKEALL -a powerpc -v esd
+	  - build all PowerPC boards manufactured either by "keymile" or "siemens":
+	      MAKEALL -a powerpc -v keymile -v siemens
+	  - build all Freescale boards with MPC83xx CPUs, plus all 4xx boards:
+	      MAKEALL -c mpc83xx -v freescale 4xx
