New target to upload bootloader

Development Platforms
3

One time per board. But ok I understand. I already read this thread and end up with this code:

import sys
Import("env")

print env.Dump()

def miss(variable):
    sys.stderr.write(
        "Error: Please specify `%s` in the board config json " % variable
    )
    exit(1)

if "BOARD" in env:
    if "bootloader.low_fuses" in env.BoardConfig():
        env.Replace(
            LOW_FUSES = env.BoardConfig().get("bootloader.low_fuses")
        )
    else:
        miss('low_fuses')
    if "bootloader.high_fuses" in env.BoardConfig():
        env.Replace(
            HIGH_FUSES = env.BoardConfig().get("bootloader.high_fuses")
        )
    else:
        miss('high_fuses')
    if "bootloader.extended_fuses" in env.BoardConfig():
        env.Replace(
            EXTENDED_FUSES = env.BoardConfig().get("bootloader.extended_fuses")
        )
    else:
        miss('extended_fuses')
    if "bootloader.unlock_bits" in env.BoardConfig():
        env.Replace(
            UNLOCK_BITS = env.BoardConfig().get("bootloader.unlock_bits")
        )
    else:
        miss('unlock_bits')
    if "bootloader.lock_bits" in env.BoardConfig():
        env.Replace(
            LOCK_BITS = env.BoardConfig().get("bootloader.lock_bits")
        )
    else:
        miss('lock_bits')
    if "bootloader.file" in env.BoardConfig():
        env.Replace(
            FILE = env.BoardConfig().get("bootloader.file")
        )
    else:
        miss('file')
    if "build.mcu" in env.BoardConfig():
        env.Replace(
            MCU = env.BoardConfig().get("build.mcu")
        )
    else:
        miss('build.mcu')
else:
    sys.stderr.write(
        "Error: Please specify in platform ini which board"
    )
    env.Exit(1)

env.Replace(
    SETFUSECMD='$UPLOADER $UPLOADERFLAGS -v -p$MCU -cstk500v1 -Ulock:w:$UNLOCK_BITS:m -Uefuse:w:$EXTENDED_FUSES:m -Uhfuse:w:$HIGH_FUSES:m -Ulfuse:w:$LOW_FUSES:m',
    UPLOADBOOTCMD='$UPLOADER $UPLOADERFLAGS -v -p$MCU -cstk500v1 -Uflash:w:$SOURCES:i -Ulock:w:$LOCK_BITS:m',
)

uploadboot = env.Alias(
    "bootloader", './$FILE',
    [
        env.VerboseAction(env.AutodetectUploadPort, "Looking for upload port..."),
        env.VerboseAction("$SETFUSECMD", "Setting fuses"),
        env.VerboseAction("$UPLOADBOOTCMD", "Uploading bootloader $SOURCE")
    ]
)

AlwaysBuild(uploadboot)
