[Xen-devel] [PATCH] xen/arm: change DomU memory property size from u64 to u32

[Viktor Mitin <viktor.mitin.19@xxxxxxxxx>]

While checking xen dom0less documentation it has been found
that domU memory property requires extra 0x0 in case of arm64.

There is no need to keep memory size in u64, 32 bits is
enough for domU memory size.

Tested that in case of arm64 dom0less domU works
without adding extra 0x0 to domU memory property with this patch.
