(Problem is, I don't have Ethernet devices on the board.) Also, I just have 2 MB of flash, so uImage + initrd + ... will take up more than 2 MB. So I have to do something like this.

This is no problem at all. There are even boards without any flash at all (for example, the PN62 board has no flash, and the U-Boot image gets loaded into RAM over PCI).

Hey WD, can you explain a bit on how you actually did this? The preboot command copies something from PCI. How / when do you write to the SDRAM over PCI? Did you do this through interrupts? Or was it something else?

Thanks, Amit.
