Hi Wolfgang,
I'm working with Nicholas on the dataflash driver for U-Boot. The dataflash is used to store big amount of data(up to 128 Mbits for the AT45DB128). In our case, we use it to store and boot an image of linux(the dataflash contains the linux zImage and the ramdisk). This dataflash can be used also for a filesystem.
regards, Hamid,

Why do we need a special command to access the DataFlash? I would like to see the same interface as for all other flash devices.
The DataFlash is a serial flash which is accessed like a serial eeprom.
That
is why we decided to create a special command to access it.
What is it being used for, then?
Concerning the other points, we will make the corrections.
Thanks.
Best regards,
Wolfgang Denk
