Serial console not enabled for passphrase prompt when using LUKS

Bug Description

I am using to install encrypted guided LVM over the serial port. It installs but the installed bootloader does not have "console=ttyO2,115200", causing the passphrase prompt to not appear on reboot. This means that I cannot enter the passphrase so the system is not bootable.

Workaround: edit the SD card FAT partition as follows:

 1. dd bs=1 skip=72 if=boot.scr of=boot.script
 2. Edit boot.script and add console=ttyO2,115200
 3. Run "mkimage -A arm -O linux -T script -C none -d boot.script boot.scr" (from the u-boot-tools package)

Changed to flash-kernel-installer as it is currently hardcoded to generate the boot.script during installation regardless of cmdline settings.
