[U-Boot-Users] [PATCH] DataFlash for AT91RM9200DK board

[Hamid IKDOUMI]

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,

What is it being used for, then?

Thanks.

Always try to do things in chronological order; it's  less  confusing
that way.
