OK.  If done properly, there shouldn't be any need to drop XIP support.  
However, given that XIP is already a specialized configuration that is 
handled by hardware experts, in the future you might have to provide at 
kernel configuration time the actual physical address of your RAM as it 
is currently done for the ROM address where the kernel image is located.
