Issue: CONFIG_HAS_DATAFLASH hooks are invasive Background: Atmel DataFlash is a serial FLASH device with an SPI interface. There is code in u-boot that pretends that it is bus-addressable. Possible solutions:
- Move DataFlash support over to the block device
infrastructure and add commands for direct manipulation of block devices. This assumes that it makes sense to look at a DataFlash device as just like any other block device.

My first reaction is.
If it walks like a block device & quacks like a block device - it's a block device.
However I've forwarded to Hamid (author of dataflash.c) && Rick (AT91RM9200DK maintainer) for their opinions.
In the absence of any evidence otherwise, I just assume Atmel wanted to show
how neatly DataFlash can be treated as bus addressable.....
