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