Hello all.

This small series contains early printk and full UART support
for i.MX 8M Mini EVKB [1].

Tested on i.MX 8M Mini only to which I had an access, but from my
understanding, this UART support should be suitable for other i.MX8M* SoCs
(those UART device tree nodes contain "fsl,imx6q-uart" compatible string).
