	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
