The kernel automatically figures out where in physical memory it should decompress itself to (CONFIG_AUTO_ZRELADDR), but the mechanism it uses to do this assumes that RAM starts at a 128MB boundary. So we must keep the board's RAM start address at a 128MB boundary. Why did you want to move VIRT_MEM up? There's plenty of space below it still, I would have thought. -- PMM
