    autoboot: add CONFIG_AUTOBOOT to allow to not compile autoboot.c · 41598c82
    Masahiro Yamada authored
    Since commit bb597c0e
    
     ("common: bootdelay: move CONFIG_BOOTDELAY
    into a Kconfig option"), CONFIG_BOOTDELAY is defined for all boards.
    
    Prior to that commit, it was allowed to unset CONFIG_BOOTDELAY to
    not compile common/autoboot.c, as described in common/Makefile:
    
      # This option is not just y/n - it can have a numeric value
      ifdef CONFIG_BOOTDELAY
      obj-y += autoboot.o
      endif
    
    It was a bit odd to enable/disable code with an integer type option,
    but it was how this option worked before that commit, and several
    boards actually unset it to opt out of the autoboot feature.
    
    This commit adds a new bool option, CONFIG_AUTOBOOT, and makes
    CONFIG_BOOTDELAY depend on it.
    
    I chose "default y" for this option because most boards use the
    autoboot.  I added "# CONFIG_AUTOBOOT is not set" for the boards that
    had not set CONFIG_BOOTDELAY prior to the bad commit.
