[PATCH 0/2] enable DM_SERIAL on imx8mn-evk and imx8mn-ddr4-evk

[Heiko Thiery]

I was only able to test it on a 8MNANOD3L-EVK board. Please help testing
this change on the other 2 eval boards (8MNANOLPD4-EVK, 8MNANOD4-EVK).

SPL not use DM_SERIAL, only U-Boot proper use DM_SERIAL, right?

Not related to your patch, I think we need add some low level debug uart
setup to have uart work as early as possible, especially for bring up 
new SoC/board.

Thanks,
Peng.

Yes only U-Boot uses DM_SERIAL.
