2015-06-05devicetree: auto-disable dts for old kernelsPetter Mabäcker
After '6392a63 rpi-base.inc: Use KERNEL_DEVICETREE by default' was introduced, kernel versions < 3.18 might not be buildable. Since full device tree support was introduced in 3.18 this change ensures that all kernel < 3.18 will automatically disable device tree. Signed-off-by: Petter Mabäcker <petter@technux.se>
2015-02-08Add support for Raspberry PI 2Andrei Gherzan
Add machine configuration file. Change the kernel image name on SD card. Use the defconfig for this machine (bcm2709_defconfig). Change-Id: I6549d5f49b1ed32ef4d44aca6f7af4234618c1a8 Signed-off-by: Andrei Gherzan <andrei@gherzan.ro>

2015-02-05devicetree: Add minimal support with RPi bootloaderFrancois Muller
[RPi DT info] https://github.com/raspberrypi/documentation/blob/master/configuration/device-tree.md#part-3-using-device-trees-on-raspberry-pi RPi bootloader detects a DT-ready kernel by checking for a specific trailer in kernel.img. Using latest raspberrypi/firmware (firmware.inc) enables this check ability. Using latest raspberrypi/tools (rpi-mkimage.bb) gives access to mkknlimg for adding the required trailer to kernel image. If KERNEL_DEVICETREE is filled in, the trailer is added to the kernel image before kernel install task. While creating the SDCard image, this modified kernel is put on boot partition (as kernel.img) as well as DeviceTree blobs (.dtb files). If KERNEL_DEVICETREE is empty, this new process isn't operated, legacy one does. KERNEL_DEVICETREE for RPi is really supported only starting from linux-rapsberry 3.18+ kernels, so as for now it defaults to empty (in machine config file).

2014-03-06sdcard_image-rpi: make rpi-sdimg image dependent on rootfs typeJonathan Liu
The rootfs may be using a filesystem type other than ext3 so it should not be hardcoded. Change-Id: I71c1a96831ce4617b24de7743fe3b70ec5822a33 Signed-off-by: Jonathan Liu <net147@gmail.com>

2014-02-09sdcard_image-rpi: Add support for u-boot and uImageAndrei Gherzan
If KERNEL_IMAGETYPE is uImage, use u-boot image as kernel.img and copy uImage too. Otherwise, use kernel image as kernel.img (as we did until now unconditionally). Change-Id: Iac46a57e4266299f2fe5746cb6957dcfc0e90443 Signed-off-by: Andrei Gherzan <andrei@gherzan.ro>
2013-11-12sdcard_image-rpi.bbclass: Allow optional compressionPaul Barker
Image files will typically contain lots of null blocks and should compress well. This will help with distribution of images over slow network links. Change-Id: Icec7454ff61cd81a2872037037a93ce01191ece5 Signed-off-by: Paul Barker <paul@paulbarker.me.uk>

2013-05-02sdcard_image-rpi: Use the size of the generated rootfsJan Schmidt
When constructing the SD card image, the code was using the inherited ROOTFS_SIZE, which is the size of the rootfs contents. When building (for example) a compressed rootfs, this allocates a partition much larger than necessary. Instead, take the size of the generated rootfs file that is about to be written into the generated image, and round it up to the IMAGE_ROOTFS_ALIGNMENT size. Fix some comments - the alignment is 4MiB, not 4KiB. Signed-off-by: Jan Schmidt <thaytan@noraisin.net> Signed-off-by: Andrei Gherzan <andrei@gherzan.ro>

2012-09-12sdcard_image-rpi: Align SD partition and optimize final SD imageAndrei Gherzan
SD image file was 4G in size but actually the rootfs partition was only 60MB (ex.: rpi-basic-image). The image file size is not fixed anymore but calculated inside this class. In this way we will setup the partition for rootfs to fit the ext file used as SDIMG_ROOTFS. By default the free space is calculated with IMAGE_OVERHEAD_FACTOR which is by default 1.3. If more free space is needed this can be overwritten. IMAGE_ROOTFS_ALIGNMENT set at 4096. This should be the best value for a SD card.

2012-07-02sdcard_image-rpi.bbclass: Change to be usable with any imageAndrei Gherzan
Instead of being inherited by a specific image recipe, this class can now be inherited globally in the machine configuration, allowing it to be used with any image. This means we can remove "inherit image", and we can also remove the IMAGE_FSTYPES modification since the machine config does this already.

2012-07-02sdcard_image-rpi.bbclass: Rewrite sdimage creation class - implemented with ↵Andrei Gherzan
parted This implementation doesn't use loop mounts, it uses mcopy to copy files to partitions. The partition creation is done with parted. Because of using these tools the IMAGE_DEPENDS was modified accordingly. Added a way of selecting the desired GPU firmware. Because we don't create the rootfs image but we rely on an already created rootfs image, the stamp is available only in the boot partition. By default the class needs an ext3 rootfs image. This is because we don't have yet a way of generating cmdline.txt in order to pass the partition type to the kernel. By default ext3 is mounted so we use this fs type until this will be selectable while generating a cmdline file. Signed-off-by: Andrei Gherzan <andrei@gherzan.ro>
