[U-Boot-Users] Paged memory?

Hi,
We are developing a custom board using the Blackfin processor and would like to use U-boot if possible. We have 8 Meg of flash that is split into 8 * 1 Meg pages, the pages being controlled by some programmable io pins. Is this sort of memory architecture supported by u-boot?
Thanks

Yes - you will have to take care of this in your flash driver, and either accept the fact that the memory commands ("md" and friends) can operate only on the current page [maybe you add a custoim command for page select], or extend the memory commands to auto-select pages.
I don't know enough about the BF processor - maybe you can also configure the memory controller to present you a virtual view of flat memory?
