Note: The backlight class device is auto-removed because it is implicitly
selected by the framebuffer.

The defconfig contained some old entries. Re-exported the defconfig to
get a clean state.

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

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.

One logo, centered, white background, no rotation.
Rotation may be set in a postinstall step later.

removes esp.:
 * lock debugging and debugging sysmbols for variables, etc.
 * support for i.MX3x, i.MX5x, i.MX6 non-ULL SoCs, i.MX8x
 * support for IPUv1, IPUv3, VPUs, GPUs
 * support for DVB and IR remote control modules

reduces (compressed) kernel size from almost 10 MB to just
under 6 MB. (uncompressed kernel is still almost twice as big as the
Rocko 4.9.88 kernel for 6ULL, though)

Add the linux-guf-5.10 recipe and copy the files form 5.4.

Do not use the
use-pkg-config-native-to-find-host-lcrypto-in-sysroot.patch because it
does not apply right now.

Also assign PREFERRED_VERSION of the linux-guf recipe weakly to be able
to overwrite this in the local.conf

Only tested with imx6guf.

cherry-picked to out current kernel the aliasing works as it worked for
previous linux ports, namely the eMMC equipped on the iMX6 Garz & Fricke
boards is mapped to mmcblk0.

Thus use this mmcblk0 mapping to refer to the eMMC.

* Split defconfig into two differnt defconfigs for the two platforms
* Enable PF1550 PMIC driver and disable PFUZE100 for imx6ullguf

Rename the linux kernel repository to linux-guf.
Switch to SRCREV="${AUTOREV}" for the kernel development.

The team decision is to rename the linux kernel repository from
linux-stable to linux-guf to show that it actually does not mirror the
linux-stable directly but uses it as a basis source for our Garz &
Fricke development.

This changes include renaming the recipe, adjusting the Gitlab URL and
renaming the PREFERRED_PROVIDER_virtual/kernel.

With this change we also want to use the bitbake AUTOREV feature to pull
the latest development kernel. Right now we do not have the release
method to pin the revision to a specific version.

Pull the latest kernel including an increase of the Backlight PWM
frequency. Together with the activated panel-dt and the previously added
gfxml2dto more then one display can be supported,

* Allow usage of commandline from bootloader
* Adapt the default commandline:
** Remove earlyprintk, should be used for debug only

* Pull the rtc-pcf8563.c source from the kernel-tree at v5.4.23
 (bfe3046ecafdd71ba6932deebe2eb357048b7bfc)
* Remove the in-tree driver from the defconfig
* Add the module to the MACHINE_ESSENTIAL_EXTRA_RRECOMMENDS for san* and
nallino platforms

- use new kernel version with all I2C devices present for testing on 400 kHz bus rate

- use new kernel with SIS9255 touch support and updated kernel's defconfig

- set kernel recipe to crurrent HEAD of GUF linux-stable
- set kernel defconfig to current guf_imx_v6_v7_defconfig
  - with appended device tree enabled
  - with default kernel command line
