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.

OpenEmbedded BSP Layer - RaspberryPi
This is the general hardware specific BSP overlay for the RaspberryPi device. It should be used with openembedded-core (not old-style org.openembedded.dev).
More information can be found at:
http://www.raspberrypi.org/ (Official Site)
http://www.distant-earth.com/ (My Site)
Build scripts patched to support making a firmware image for the RaspberryPi with Angstrom can be found at:
http://github.com/Angstrom-distribution/setup-scripts
When not depending on meta-openembedded and not using systemd, you may need to mask few recipes requiring systemd or other recipes not included in your distribution of choice.
You can achieve this by adding something like the following to local.conf:
BBMASK = "meta-raspberrypi/recipes-multimedia/libav|meta-raspberrypi/recipes-core/systemd"
You can adjust the BBMASK for any .bbappends that your distribution does not contain recipes for.
The core BSP part of meta-raspberrypi should work with different OpenEmbedded/Yocto distributions and layer stacks, such as:
- Distro-less (only with OE-Core).
- Angstrom (main focus of testing).
- Yocto/Poky.
This layer in its entirety depends on:
URI: git://git.openembedded.org/openembedded-core branch: master revision: HEAD
URI: git://git.openembedded.org/meta-openembedded branch: master revision: HEAD

Yocto BSP Layer - RaspberryPi
This layer depends on:
URI: git://git.yoctoproject.org/poky branch: master revision: HEAD
URI: git://git.openembedded.org/meta-openembedded branch: master revision: HEAD
How to use it:
- source poky/oe-init-build-env rpi-build
- Add needed layers to bblayers.conf:
- meta-raspberrypi
- meta-openembedded/meta-oe 3 Set MACHINE to raspberrypi in local.conf
- Add to local.conf: BBMASK = "rpi-zram-service"
- bitbake rpi-hwup-image
- dd to a SD card the generated sdimg file (use xzcat if rpi-sdimg.xz is used)
- Boot your RPI.
Optional - compressed deployed files:
- Overwrite IMAGE_FSTYPES in local.conf IMAGE_FSTYPES = "tar.bz2 ext3.xz rpi-sdimg.xz
- Overwrite SDIMG_ROOTFS_TYPE in local.conf SDIMG_ROOTFS_TYPE = "ext3.xz" *Accommodate the values above to your own needs (ex: ext3 / ext4).
Optional - GPU firmware:
By default the GPU firmware shipped is arm192. You can overwrite this using the variable RPI_GPU_FIRMWARE with one of the values below.
arm128 : 128M ARM, 128M GPU split
arm192 : 192M ARM, 64M GPU split
arm224 : 224M ARM, 32M GPU split
arm240 : 240M ARM, 16M GPU split
