In rk3328, some function pin may have more than one choice, and muxed with more than one IO, for example, the UART2 controller IO, TX and RX, have 3 choice(setting in com_iomux):
- M0 which mux with GPIO1A0/GPIO1A1
- M1 which mux with GPIO2A0/GPIO2A1
- usb2phy which mux with USB2.0 DP/DM pin.
This suppose to be set in SPL, but the U-Boot is also design to co-work with Rockchip SPL(miniloader) which may not setting this config, let's set this config to make sure the UART2 TX/RX working in U-Boot.
