Using secondary UART for board initialization

Hi all, I need to write to (and read from) a UART during board initialization that is not the same UART the U-Boot serial console is running on. I'm using CONFIG_DM_SERIAL so I've extended my .dts to enable the additional UART (including pinmux registers). In my board init code I can find the ser
