IMX8MP Custom board | How to change the debug uart from the uart2 to uart1 for both u-boot & kernel

[Nigesh247]

Hi all , 

On i.MX8MP, the default early debug / console output comes on UART2.I want to move the entire boot console to UART1 instead.What is the correct and complete procedure to do this on i.MX8MP?

If someone has already done this, please guide me exactly which changes are needed and in which files  to move the debug UART from UART2 to UART1 on i.MX8MP
