The rpi-mkimage tools are no longer used. Recent Raspberry Pi firmware can
directly boot a Linux kernel image using device tree and mainline u-boot
supports Raspberry Pi without the use of these tools.

The repository used by u-boot-rpi has not been updated since 2012. In the
meantime, mailine u-boot has gained Raspberry Pi support. All we need to do is
set UBOOT_MACHINE to an appropriate value in the machine config files.
Currently configs are only provided for raspberrypi and raspberrypi2. The master
branch of u-boot now also appears to have a config file for raspberrypi3 so
support for this can be added in the future when u-boot is upgraded in oe-core.
The mainline u-boot recipe creates the file "u-boot.bin" instead of
"u-boot.img".

The support for PiTFT 28 inch resistive touchscreen is optional
and can be enabled by adding below in local.conf:
MACHINE_FEATURES += "pitft pitft28r"
While at it also fix a minor typo in README.

- Add support to build overlays for PiTFT22 in the kernel.
- Setup a basic configuration for the driver
The PiTFT22 support is optional and can be enabled by adding below in
local.conf:
MACHINE_FEATURES += "pitft pitft22"
This patch also includes restructuring of kernel patches per kernel version
specific directories.

On fido and earlier branches, ${libexecdir} depends on ${BPN} so it
is not a good choice as ${libexecdir} is different depending on the
recipe name.
For example, rpi-mkimage would install mkknlimg to:
[...]/sysroots/x86_64-linux/usr/lib/rpi-mkimage
but linux-raspberrypi would look for mkknlimg in the path:
[...]/sysroots/x86_64-linux/usr/lib/linux-raspberrypi
To resolve this, we use ${bindir} instead as it doesn't depend on
${BPN} in fido and earlier branches as well as in the master branch.

Add basic support for PiTFT display by using device-trees.
In order get it working below configurations must be active in
local.conf:
MACHINE_FEATURES += "pitft"
- This will enable SPI bus and i2c device-trees, it will also setup
framebuffer for console and x server on PiTFT.

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).
