[U-Boot] Question about device tree usage and ranges

[Aaron Williams]

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.

OF: ** translation for device console at 0 **
