of_fdt.h should be enough.

Also I have looked at others arch and take a look at

1b10cb21d888c021bedbe678f7c26aee1bf04ffa
ARC: add support for reserved memory defined by device tree

where they also enable OF_RESERVED_MEM to call fdt_init_reserve_mem()

The same here
4e7c84ec045921dacc78d36295e2e61390249665
xtensa: support reserved-memory DT node

and here
9bf14b7c540ae9ca7747af3a0c0d8470ef77b6ce
arm64: add support for reserved memory defined by device tree


Please note this in commit message.

Thanks,
Michal
