Where does the memory for grant tables get allocated from (Xen ARM)

Apologies if posted in wrong list.

I am investigating the use of Xen on an ARMv8 SoC and I want to share a block of memory between Dom0 and DomU.
I understand that I can use the grant table mechanism to setup shared pages.
My question is related to where does the physical memory shared get allocated from?
My particular use case would be to share a block of on-chip-memory (located inside my SoC) which is of course located at a fixed physical address, can I do this with Xen?
