Unable to implement board fdt-fixup for imx8m CPU

[Hugo Villeneuve]

Hi,
according to this document:

    doc/develop/driver-model/fdt-fixup.rst

it is suggested that boards implement the board_fix_fdt() function to tweak the device tree. I am trying to do just that, but unfortunately I cannot because the following source file already has an implementation of board_fix_fdt():

    arch/arm/mach-imx/imx8m/soc.c

For all boards using a imx8m CPU, how can we implement board_fix_fdt()?

Thank you.
