====================================================

- Linux NXP Vendor Kernel v6.6.23-2.0.0-phy10 (based on NXP tag lf-6.6.23-2.0.0)
- U-boot v2024.04-2.0.0-phy7 (based on NXP tag lf-6.6.23-2.0.0)
- Yocto 5.0.4 (Scarthgap)
- Qt 6.7
- OP-TEE 4.1
- RAUC 1.12

Tested Yocto Images:
--------------------
- phytec-qt6demo-image:
  * phyboard-pollux-imx8mp-3

- phytec-vision-image:
  * phyboard-pollux-imx8mp-3

- phytec-provisioning-image:
  * phyboard-pollux-imx8mp-3

- phytec-securiphy-image:
  * phyboard-pollux-imx8mp-3

- phytec-headless-image:
  * phyboard-pollux-imx8mp-3


Build Environment:
------------------
- Ubuntu 20.04 64-bit

New Features:
-------------
- Kernel, Device Tree and Device Tree Overlays are now stored and loaded in a FIT Image Container
- Switch to U-Boot standard boot for bootflow configuration
- Support EFI boot
- Using now poky kernel fragment handling and using new kernel defconfig "imx8_phytec_defconfig"
- Camera:
  - Switch to Linux upstream driver for phyCAM-L serializer and deserializer.
  - The VM-017 (ar0521) via phyCAM-L now runs with a 26.66 MHz input clock due to the switch to
    the serializer upstream driver.
  - Overhaul of the existing camera examples:
    - Consolidation of examples that share the same code base.
    - More descriptive output, so it is easier for users to reconstruct it
      to their own needs.
- Security:
  - FIT Image verification now uses public keys instead of HAB
  - FIT Image is build with poky kernel-fitimage class
  - Only load 'overlays' variable from bootenv.txt
- RAUC:
  - U-Boot: Only load RAUC related variables from eMMC environment

Issues fixed:
-------------
- Reenabled Qt6 demo "qtphy" multimedia page
- HDMI audio workes now even when PEB-AV-10 overlay is not applied

Defeatured:
-----------
- PEB-AV-12 support

Known Issues/Limitations:
-------------------------
- Reduction of CMA size to half for 1GiB RAM SoM
- Upper USB port on X5 connector doesn't work reliable in host mode
  in bootloader
- Increased resume duration during suspend to RAM
- With Linux 6.6.23, a change in the MMC stack occasionally prevents switching
  the eMMC boot partitions after a RAUC bundle update. A fix is already included
  upstream, see the following link for an overview:
  https://github.com/rauc/rauc/discussions/1363
  A patch for linux-phytec-imx was backported after this release, and is
  available through
  https://github.com/phytec/linux-phytec-imx/tree/v6.6.23-2.0.0-phy
  The fix will be automatically included with upcoming BSP releases.
