AM6442: Can debug U-boot with errata i2331?

Hi

May I have question about AM64x errata i2331 CPSW: Device lockup when reading CPSW registers?

My customer is developing AM64x.

Q1 : 

Is there any plan update silicon for repare errata i2331?

Q2 : 

My custome heard that we could not debug SPL and U-boot by errata i2331.

Because the errata workaround need to warm reset.

Is there another way to avoid errata?

Q3 : 

Is there any critical bug for use AM64x, peripherals?

Thanks,

GR
