Upgrading to 23.05.3

 * Sysupgrade from 21.02 to 23.05 is not officially supported.
 * ipq40xx EA6350v3, EA8300, MR8300 and WHW01 require tweak to the
   U-Boot environment on update from 22.03 to 23.05. Refer to the Device
   wiki or the instruction on sysupgrade on how to do this change.
   Config needs to be reset on sysupgrade.

Known issues

  * lantiq/xrx200 target shows error messages in DSA switch
    configuration of the integrated GSWIP switch. (see:
  * OpenWrt 23.05.3 was signed with the wrong signing keys. The keys
    from OpenWrt snapshot were used for OpenWrt 23.05.3, OpenWrt
    23.05.2, OpenWrt 23.05.0 and the release candidates. A later OpenWrt
    23.05 service release will use a different key.
