Sorry for top posting. I am on outlook web access. There may be some limitation on fdt relocation. Without setting fdt_high, u-boot relocates the device tree toward the end of useable memory. I haven't got a chance to debug why it doesn't work.
This patch is to disable the relocation by default. A magic number 0xa0000000 doesn't make much sense here.

I'd hope fdt_high wouldn't cause the device tree to be relocated beyond the end of memory, or in reserved memory... -Scott _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
