Currently, the serial console is hardcoded to ttyS0 in the bootloader element. This is a challenge for users that want to build images for some baremetal servers. Supermicro servers, for example, use ttyS1 for the serial over lan interface. This patch adds a new environment variable DIB_BOOTLOADER_SERIAL_CONSOLE that can be set to override the default.

========== bootloader ========== Installs ``grub[2]`` on boot partition on the system. In case GRUB2 is not available in the system, a fallback to Extlinux will happen. It's also possible to enforce the use of Extlinux by exporting a ``DIB_EXTLINUX`` variable to the environment. Arguments ========= * ``DIB_GRUB_TIMEOUT`` sets the ``grub`` menu timeout. It defaults to 5 seconds. Set this to 0 (no timeout) for fast boot times. * ``DIB_BOOTLOADER_DEFAULT_CMDLINE`` sets parameters that are appended to the ``GRUB_CMDLINE_LINUX_DEFAULT`` values in ``grub.cfg`` configuration. It defaults to ``nofb nomodeset vga=normal``. * ``DIB_BOOTLOADER_SERIAL_CONSOLE`` sets the serial device to be used as a console. It defaults to ``hvc0`` for PowerPC, ``ttyAMA0,115200`` for ARM64, otherwise ``ttyS0,115200``.
