Perhaps just loading Xen at 0x80000000 might also avoid the copy?

I am running using simulator. All image should be loaded into DRAM before system power up. uboot is loaded at this address, so I change to load xen at 0x80200000. And hacked uboot to avoid copy. Since from [0], just to save memory, it hurts nothing else to load xen at 0x80200000.

Thanks,

Peng.
