Physical memory loading into UVM

What is right way set physical memory UVM for ?
I guess, that's "uvm_page_physload", but I'm in some
doubt about that.

For the instance, I'm going to port kernel to Psion
revo plus. 
It has ARM710T and 16 Mb RAM in 4 non contiguous
memory chunks.
LCD buffer is mapped on RAM too.

I would like to reuse existing arch/arcm code
including pmap, of course.
In this case, I only need to define follow consts: 

#define	VM_PHYSSEG_MAX		4
#define	VM_PHYSSEG_STRAT	VM_PSTRAT_BSEARCH
#define	VM_PHYSSEG_NOADD

and next, call the uvm_page_physload for define
physical memory regions and correct loading them into
UVM.
Is it correct ?

Please advice me.

Thanks,
Arthur
