Hi,
In my device tree I need to translate some address via ranges but I'm running into some issues. If I use ofnode_get_addr_size() it is not using the #address-cells and #size-cells nor is it performing the ranges translation. It always assumes #address-cells and #size-cells is 2 and doesn't translate. Is this by design?
If, on the other hand, I use ofnode_get_addr_size_index, it is having problems on ARM64. One problem I see is in of_translate_one in fdt_support.c. Shouldn't there be a fdt32_to_cpu or fdt64_to_cpu for the address after the memcpy in of_translate_one? I'm seeing the wrong endian address and size show up.
