But my (limited!) understanding is that it's not a platform problem you are solving, but one of this special kind of controller, which nobody else would ever run into. Is this understanding correct?

Hard- ware has limitations, software doesn't. It's a real shame that Turing machines are so poor at I/O. _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
