Build Environment:
------------------
- Ubuntu 22.04 64Bit


Known Issues:
-------------
- kernel:
  * Small performance drop on IO-operations with external devices when
    LOW-POWER-IDLE state is active (CONFIG_CPUIDLE)
- phyGATE-Tauri-S RS232 / RS485:
  * At the same time only '2x RS232' or '1x RS232 and 1x RS485' can be used on
    phyGATE-Tauri-S. Right now '1x RS232 and 1x RS485' is the default.
- PEB-WLBT-05-15x modules (5 GHz option) don't work. They are using Sterling-LWB5 chips,
  which is EOL.
- default kernel CMA allocation of 256MB fails on phyboard-segin-imx6ul-2, -4,
  -5, -7 and phygate-tauri-s-imx6ul-1 machines with 512MB of RAM. One can fix
  the issue in runtime by entering Barebox bootloader console and executing the
  following command: nv linux.bootargs.cma=cma=128M

Notes:
------
- 'phytec-security-image' is renamed to 'phytec-securiphy-image'.
- 'security' distro is renamed to 'securiphy'.
