TPS659037: Life Cycle Information of AM5728BABCXEA, TPS6590379ZWSR and TPS51200DRCR

Part Number: TPS659037

Hi All,

We are in the process of designing a new product using the Sitara Processor  AM5728BABCXEA

Life cycle
1- Regarding the availability of the AM5728BABCXEA, I read the longevity policy TI has committed to. 
This processor is still under an "Active" Status.
It is critical for us as any future change might have a significant impact on the workload associated with a processor change, especially the certifications approvals. 
Is there a way that TI can confirm that processor AM5728BABCXEA will be available for at least the next 10 years starting from now?
2- PMIC TPS6590377ZWSR has been discontinued.  As per document / Table 2 Last Row (SLIU011F–March 2015–Revised April 2018 ) the TPS6590379ZWSR is the recommended Newer OTP Version, is this still valid? and can you confirm that it will be available for at least the next 10 years?
3- Is the TPS6590379ZWSR completely drop-in compatible with the TPS6590377ZWSR?  As per SLIU011F Table 2 (last row) "GPIO_2 was added to the sequence at the same time as SMPS3".  In our design GPIO_2 has been connected to ground via a 10K pull-down resistor.
4- TPS51200DRCR Sink and Source DDR Termination Regulator.  Same question, can you confirm that it will be available for at least the next 10 years?
