    cmd/fdt: Make fdt get value endian-safe for single-cell properties · b05bf6c7
    Andreas Färber authored
    On a Raspberry Pi 2 disagreements on cell endianness can be observed:
      U-Boot> fdt print /soc/gpio@7e200000 phandle
      phandle = <0x0000000d>
      U-Boot> fdt get value myvar /soc/gpio@7e200000 phandle; printenv myvar
    Fix this by always treating the pointer as BE and converting it in
    fdt_value_setenv(), like its counterpart fdt_parse_prop() already does.
    Consistently use fdt32_t, fdt32_to_cpu() and cpu_to_fdt32().
    Fixes: bc80295b ("fdt: Add get commands to fdt")
