IMHO, Since we are moving i.MX stuff with SPL and dt support a lot of
code can be prevented from board files like pinctrl(PADS), UART, MMC,
I2C, FEC,USB. Please better to start adding new board with
new-features which are supported this will certainly improve
maintainability and align with latest u-boot features.

thanks!
