      cfi flash: add status polling method for amd flash · e5720823
      Thomas Chou authored
      This patch adds status polling method to offer an alternative to
      data toggle method for amd flash chips.
      
      This patch is needed for nios2 cfi flash interface, where the bus
      controller performs 4 bytes read cycles for a single byte read
      instruction. The data toggle method can not detect chip busy
      status correctly. So we have to poll DQ7, which will be inverted
      when the chip is busy.
      
      This feature is enabled with the config def,
      CONFIG_SYS_CFI_FLASH_STATUS_POLL
