We don't want to use the machine overrides from the meta-freescale
layer. Therefore, we disabled the filter mechanism and re-added
the old SoC names.
To reflect this change, the files have been moved to the correct folders.

NXP suggests using the dma-heap allocator instead of the ION memory
manager from kernel 5.15.5 onwards.

Activated/Enabled modules/drivers that might be related to the
Hantro VPU and DRM.

The defconfig for the 5.15.5 kernel is used by the mx8mm and mx8mp.
The location "imx8mguf" is only accessible by the mx8mm. To make
the config available to the mx8mp, the config folder was renamed.

Note: imx8mguf is the machine name of the mx8mm. This is a known bug
and will be fixed in the future.

For the i.MX8 devices, we use the 5.15.5 Yocto kernel provided by NXP.

* maxTouch:udev: Add udev rule to skip maxTouch fwr loading fallback

  The current version of the atmel_mxt_ts driver tries to load a controller
  configuration on each driver probe. However, if no config is provided or
  can't be provided because the driver is built-in, the driver probing process
  is delayed by 60 seconds because of a sysfs firmware load fallback.
  Added a udev rule that automatically cancels the sysfs firmware fallback.

The tools recipes still use SSH as protocol for the checkout.
Since we have opend our repository to the public, SSH isn't available
anymore. Because of this, we switch to HTTPS as protocol.

  Don't use linux-imx-kuk to allow two different entries in the
  SRCREV.conf to specify the SRCREV independently for the 5.10 and
  the 5.15 version. As the 'kuk' part is not in this branch it also
  makes sense to remove the appendix.

  The subfolder and prefix is now seconorth instead of keithkoep and guf.

We disable the creation of symlinks for the kernel.
Because of our FAT boot partition, the symlinks lead to errors
during the installation process.
Disabling the link creation fixes the installation, but leads to
another error during the pack operation of Flash-N-Go-System.
This new issue needs to be fixed separately.

The kernel includes and recipes have been renamed to seconorth.
Also the defconfigs have been moved to fitting folders.

The Yocto build is broken because of the missing links for the Kernel.
Since removing the links from the deploy doesn't fix our issue with
the boot filesystem we reenable them.

In Yocto Kirkstone, a new way to create kernel symlinks was added.
Since we use a FAT partition for the Kernel, symlinks are not supported.
Disable the creation of symlinks.

* Conversion of the OVERRIDE syntax
* New folder names for NXP specific folders

The most recent mainline LTS 5.15 kernel is 5.15.29. So use this one for
the limux-guf implementation.

The port is based on on a cleaned linux-guf 5.10.104.

(cherry picked from commit 4f5e5c7d)

Update the kernel to 5.10.104. This should pull the latest security
fixes, i.e. for CVE-2022-0847.

With this it seems to be necessary to disable
CONFIG_STACKPROTECTOR_PER_TASK to build it inside Yocto dunfell.
It seems to be a problem of missing headers inside gcc-plugin.

Remove the PREFERRED kernel variables from imx6ull, that are derived
from guf.inc.

BCS 746-000735

Remove CONFIG_STACKPROTECTOR_PER_TASK defconfig as it breaks the build.

With this enabled and with the jump from Linux 5.10.57 to 5.10.104 I see
the following error:
```

Seems to be similar to https://lists.yoctoproject.org/g/poky/message/12619

Form my point of view this is a missing header inside the gcc-plugin
package, and should be fixed there. However, right now we just remove
the feature from the kernel.

Enabled wireguard in defconfig. Removed wireguard-modul dependencies for
wireguard-tools since wireguard is already integrated in kernel 5.10.
