Hi Bala,

I have applied the series to u-boot-at91/next here :
https://source.denx.de/u-boot/custodians/u-boot-at91/-/tree/next

Can you double check that everything is fine ? I have done some edits on 
rebasing.

Otherwise, the series will go as a PR to 2023.04 from the at91 tree once 
the merge window opens.

Thanks,
Eugen
