Re: [U-Boot-Users] Atmel DataFlash hooks.

Hello!

I dont see why you should need to call any "open" routine since the dataflash is active before u-boot has even started and does not need any initialization sequence.

There could be further initialization of Dataflash devices at later time: - Dataflash card may be plugged into the board when U-Boot is already running, e.g. for firmware updates. - A Dataflash can be placed on an extension board which will be powered up later during system start-up. This could also require a Dataflash to be initialized later. Probably such open() function could check if the extension board is present and powered.
