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