Simon,

Do you think fdt_addr_t should be phys_addr_t? According to the comments you put
in file, "A typedef for a physical address". If yes, I can change the commit
message.

On the other hand, if we want to keep the current typedef, we can use Albert's
PRIu64 technique, we then don't have to define the format string.
