The build-time kernel command line (as defined by the CONFIG_CMDLINE config parameter) is not respected by the RPI bootloader, and instead any custom command line must be suplied via the cmdline.txt file in the boot partition. This patch modifies the linux-raspberrypi recipe to generate a cmdline.txt file that corresponds to the build-time configured command line, and it also modifies the sdcard_image-rpi.bbclass to include this file in the generated SD card images.
