NOTE
BSP functionality in some configurations and use cases, or your own/added
software functionality, may be affected by an erratum. We have made our
bestattemptatprovidingsoftwareworkaroundrequirementsandBSPstatus
foreacherratuminthisdocument.Whether a software workaround hasbeen
implemented in the BSP or not, the user should evaluate his specific use
cases and take any (additional) necessary actions to prevent the occurrence
or impact of each erratum. Go through your support channel if you have any
