Given that the kernel is being loaded out of flash (with all drivers compiled in), and that the only reference to the IDE drive that U-Boot really knows about is a commandline parameter passed to the kernel, would it cause any conspicuous problems to remove ATA support from U-Boot, or does the kernel depend on hardware information that U-Boot is providing (I notice there's a "U-Boot" section in the kernel config)?
Victor,
It's been a little while since I looked at it, but I don't believe there is any reason why U-Boot needs to have the IDE/ATA stuff built-in unless U-Boot is going to use it. I'm pretty sure it doesn't communicate w/ the kernel about it (i.e. IDE) at all. Of course, YMMV... :-)
