With newer kernels (>=3.18) that supports device-trees I2C
should be enabled with device-trees.
This is now support by adding:
ENABLE_I2C = "1"
in local.conf
This will enable the dtparams:
i2c1
i2c_arm

It doesn't make sense to install to ${libexecdir}/rpi-mkimage as it
changes the path on fido and earlier branches from:
[...]/sysroots/x86_64-linux/usr/lib/rpi-mkimage
to:
[...]/sysroots/x86_64-linux/usr/lib/rpi-mkimage/rpi-mkimage
Using ${libexecdir} instead of ${libexecdir}/rpi-mkimage preserves
the path for fido and earlier.

The rpi-mkimage tools are installed ${libexecdir}/rpi-mkimage within
native sysroot, where ${libexecdir} resolves to /usr/libexec. This caused
the build to fail due to recipe trying to access ${libdir}/mkimage. Fix
the paths to use an unambiguous STAGING_LIBEXECDIR_NATIVE so that a
proper location is used.

For consistency with other recipes that look for mkimage
tools (u-boot-rpi, linux-raspberrypi) under ${libexecdir}/rpi-mkimage,
make sure that the tools are installed at the proper location.

With the newer kernels that use device tree, the SPI bus is only
enabled by a device tree setting. This is now supported by adding
ENABLE_SPI_BUS = "1"
in local.conf

[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).

PRINC is now obsolete and the PR Service should be used instead to keep PR
values incrementing on change.
A patch has also been submitted to openembedded-core to bump the appropriate PR
values so that PR doesn't move backwards. This patch should only be applied
after that patch, and only to branches which include that patch (ie. if that
patch doesn't go into daisy in oe-core, this patch shouldn't go into daisy in
meta-raspberrypi).
