When OF_LIVE flag is enabled on a 64 bits platform, there is an issue when dev_read_addr() is called and need to perform an address translation using __of_translate_address().
In case of error, __of_translate_address() return value is OF_BAD_ADDR (wich is defined in include/dm/of.h to ((u64)-1) = 0xffffffffffffffff). The return value of dev_read_addr() is often compared to FDT_ADDR_T_NONE which is defined as (-1U) = 0xffffffff. In this case the comparison is always false.
To fix this issue, define OF_BAD_ADDR to FDT_ADDR_T_NONE.
