+NXP i.MX8MP
+-----------
+
+* The i.MX8MP SoC UID really is 128bit. With this release all 128bit
+ are used for the SoC UID, previously only 64bit were used. This will
+ result in a different SoC UID and consequently a different machine_id
+ when systemd.machine_id is passed to Linux. If you need to keep the
+ previous 64bit SoC UID for compatibility reasons enable
+ CONFIG_ARCH_IMX8MP_KEEP_COMPATIBLE_SOC_UID
