[U-Boot] What is CONFIG_HAS_DATAFLASH?

[Timur Tabi]

Can someone tell me what CONFIG_HAS_DATAFLASH does?

The reason I ask is that I'm trying to use
CONFIG_CFI_FLASH_USE_WEAK_ACCESSORS, but I noticed that the "md"
command does not use the flash_readX primitives when I ask it to
display memory from a flash address.  In examining do_mem_md(), I
noticed CONFIG_HAS_DATAFLASH.
