AM6442: Change boot console to main_uart5 from main_uart0

Part Number: AM6442

Tool/software:

Hi,

I am trying to change the u-boot console from main-uart0 to main-uart3 with TMDS64EVM, but fails so far.

I've read this topic, https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1240439/am625-changing-u-boot-console-from-uart0-to-uart4/4714870#4714870, and the situation, no clock definition for main_uart3, seams to be same. 

Our custom board's boot console is to be main_uart5 or main_uart6, but, currently I am developing u-boot for our board with TMDS64EVM and SDK10.00.

Could you please advise how to fix this problem?
