When fdt_add_reserved_memory() is called to add a memory region, we unconditionally add a node for that region. However there might be an existing region node in the DT already, or there might be an overlapping region. The Linux kernel will complain in those cases. Cover the simple case of the region already existing in the DT, as this is what we actually see on the Allwinner H616: The mainline DT contains a node reserving the memory for TF-A, in case the DT changed by TF-A itself is not given to the kernel. Our code always adds a region, making the kernel complain - albeit without further consequences. Covering all cases of overlapping regions would blow up the generic DT code too much, so just add a simple check for an existing region completely containing the to-be-added region, simply bailing out in this case. This prevents the kernel warning for the Allwinner H616. This code requires a function from fdt_wrappers.c, so we have to include that file for platforms that use the fdt_add_reserved_memory() function (rpi4 and versal2).
