  12         Usage: MAKEALL [options] [--] [boards-to-build]
  13
  14         Options:
  15           -a ARCH,   --arch ARCH       Build all boards with arch ARCH
  16           -c CPU,    --cpu CPU         Build all boards with cpu CPU
  17           -v VENDOR, --vendor VENDOR   Build all boards with vendor VENDOR
  18           -s SOC,    --soc SOC         Build all boards with soc SOC
  19           -l,        --list            List all targets to be built
  20           -m,        --maintainers     List all targets and maintainer email
  21           -M,        --mails           List all targets and all affilated emails
  22           -h,        --help            This help output
  23
  24         Selections by these options are logically ANDed; if the same option
  25         is used repeatedly, such selections are ORed.  So "-v FOO -v BAR"
  26         will select all configurations where the vendor is either FOO or
  27         BAR.  Any additional arguments specified on the command line are
  28         always build additionally.  See the boards.cfg file for more info.
  29
  30         If no boards are specified, then the default is "powerpc".
  31
  32         Environment variables:
  33           BUILD_NCPUS      number of parallel make jobs (default: auto)
  34           CROSS_COMPILE    cross-compiler toolchain prefix (default: "")
  35           MAKEALL_LOGDIR   output all logs to here (default: ./LOG/)
  36           BUILD_DIR        output build directory (default: ./)
  37           BUILD_NBUILDS    number of parallel targets (default: 1)
  38
  39         Examples:
  40           - build all Power Architecture boards:
  41               MAKEALL -a powerpc
  42               MAKEALL --arch powerpc
  43               MAKEALL powerpc
  44           - build all PowerPC boards manufactured by vendor "esd":
  45               MAKEALL -a powerpc -v esd
  46           - build all PowerPC boards manufactured either by "keymile" or "siemens":
  47               MAKEALL -a powerpc -v keymile -v siemens
  48           - build all Freescale boards with MPC83xx CPUs, plus all 4xx boards:
  49               MAKEALL -c mpc83xx -v freescale 4xx
