I did primary development on the P1022DS, so maybe I can help. It's been a while since I've worked on it, though. First, note that there are two versions of the P1022DS DTS: one is 32-bit, and the other is 36-bit. This was back when Freescale's SOCs were transitioning to 36-bit physical addresses. So if you're never going to have more than 2GB of RAM in your system, you can use 32-bit physical addresses in the DTS. Can you explain the problem again? Like I said, it's been a while, but I have a hard time believing that you've discovered a new problem on the P1022 that hasn't already been solved. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
