when bootup the ls2085ardb, the board is REV D, sdk version is SDK-V2.0-1701, uboot and linux both can not detect the SPI NOR flash, MT25QU512ABB8ESF-0SIT.

under uboot command line:

      => sf probe

      Invalid bus 0 (err=-19)
      Failed to initialize SPI flash at 0:0 (error -19)

      => sf probe 1:0
      SF: Unsupported flash IDs: manuf 00, jedec 0000, ext_jedec 0000
      Failed to initialize SPI flash at 1:0 (error -22)

the  log when start kernel:

      [    2.205359] m25p80 spi0.0: unrecognized JEDEC id bytes: 00, 00, 00
